Basically comes down to being "advertiser friendly".

Because of that:

• Platforms like YouTube and TikTok downrank you through the algorithm because they can't put ads on your video to monetize it
• People probably want to upload talks to YouTube, so it's taken into account even if there's nothing preventing you at the actual conference.
• People don't want to be censored on those platforms, so other terms are reused to avoid angering the algorithm (so we got, unalive, PDF files, and all that stuff)
• It bleeds into the common language.

That's not new: there's a reason there's a million way to talk about taking a shit. Everytime it becomes too popular/"gross", a new one is born that's supposedly more classy. Same thing happened with toilets/bathrooms/restrooms/water rooms. I don't know why we still try to pretend we don't all take a shit every now and then.
