Of course it requires some tinkering and is not accessible to all users.

Yeah, that's the point. None of that helps normies who just want to buy the first product they see and have it "just work."

(And I say "first product they see" because, although Tasmota/ESPHome/WLED devices are available from e.g. Amazon, if not brick-and-mortar stores, if you look hard enough, they're definitely not what Amazon pushes at you. Amazon wants you to fall for their marketing and infest your house with Alexa so they can exfiltrate even more personal data, up to and including the floor plan if you buy one of their affiliated smart vacuums.)
