I believe that's what Louis Rossmann does on a regular basis on his channel.

"And I'll happily edit out this summary of my horrible experience with Factor Meals for $1,050 per video!"

Comedian Frankie Boyle has a funny bit about blackmail sponsorships where you threaten to say negative shit about a company if they don't pay you. Like, you're watching Law & Order and suddenly it's

"Caught another pedo Sarg."

"Oh? What was he doing when you caught him?"

* faces camera *

"Eatin Walker's Crisps®" .

"This video is in spite of..."

If I had a popular YouTube channel, I’d definitely do this for Magic Spoon after it made everyone in my house violently sick.

People remember names more than opinions. It wouldn't surprise me if this was still a net gain for the company.

"This video was sabotaged by FedEx. This product I'm reviewing was ordered twice. The first time, it was damaged by the delivery driver."

Benn Jordan did that at the end of his Flock Safety video, shit-talking some companies that keep bugging him for sponsorships

There's plenty of 20-60 minute long anti-ads for Nestle.

These sponsorships already seem like anti ads. If you buy crap from influencers, that's on you.

This video is sponsored by Weyerhauser! We're destroying pretty much every ecosystem in the world, and gobble up public land like it's required to survive!

Also we'll buy all of the land around public land and illegally close off access to said public land!

But mostly the destruction of the environment! Fuck you! We're going to clear cut everything as fas as possible. You don't want to support us? Fuck you! Now we're going to close a mill that's going to devastate a small logging town! You do support us? Fuck you! We'll harvest trees so small the mills we have can't process them, and we'll close those mills too! Either way we're going to blame the owls for not being able to raze nature to dust for a quick buck!

Weyerhauser! Fuck you! We own your country!

Road Guy Rob on YouTube does parody sponsorship bits, making fun of things like VPN ads sometimes, when thanking his viewers for supporting him.

I will say this about regular sponsorship - and if you're a company bribing Youtubers to shill your shit, take heed:

Whenever a Youtuber interrupts their content to sell me garbage I don't want (and SponsorBlock doesn't catch it), I take note of the company and it goes in the very long shit-list of companies I try to avoid patronizing.

The more Youtubers that company bribes, the higher it rises in my shit-list.

The more the Youtuber tries to seamlessly weave the plug into their narrative, to sneakily make me watch it by not realizing they've switched to the plug, the higher the company they shill for rises in my shit-list - and this one annoys me no end, so the companies that pay Youtubers to make clever seamless transitions to the plugs go very quickly to the top. If you're going to waste my time with your fucking shill job, at least be honest about it.

When a company is on my shit-list, I will go the extra mile and then some to never buy anything from it, even if it sells the best and only product I really want. Fortunately, they rarely do: it's always shit.

Examples of companies at the very top of my shit-list:

NordVPN (or any VPN supplier I hear about on Youtube really)
BetterHelp
Brilliant
...

They can all fuck right off.

I do make an exception for those Youtubers who shill for quality content platforms that are alternatives to Youtube, for documentary and science videos and such, like Curiosity Stream. Not because I like the shilling, but because they advertise a service that competes with Google and that always gets my vote.

That could work on PeerTube (like a nice fad).

That's kinda what behind the bastards does. There are definitely better ad breaks than this, but they do this type of thing a lot.

TK Jewelers is a scam.

The jewelry's fake.

Watch exploded on date... Bent wrist, thing fucking exploded.

Benn Jordan did exactly this in his recent video on AI police cameras (at the 31:00 mark)

And now a message from the national apple institute: FUCK PEARS!

The youtuber popular Papameat did this with Swig when he was reviewing and making fun of the show secrets lives of Mormon house wives.

Every 5 minutes was a sponsored swig break, where he would talk about how shit their soda is and how dumb it is to shop there.

If I ever get into making youtube videos one thing I'd want to do the moment I get contacted by some stupid company like factor is make my own little ad where I put a little ipecac on the food and repeat the companies name while I vomit up everything from that week, see if that would get them to leave me alone

One of the things I absolutely hate is how every YT sponsor is thanked for "making this video possible".

It is perfectly possible to make a well produced video without sponsors or merch, even if you work full time you can do it on the weekends, it will take far longer, sure, but the video would not be impossible to make just because you don't have sponsors.

Sure it is a technicality, but an important one.
