They've captured the online video provider market by price dumping in a way nobody but Google could afford, and have become THE video website. Now they're implementing restrictive measures in a negligent manner that affect first-aid videos that people have come to rely on.

Google clearly has the AI know-how to label when videos are important medical videos. They could skip ads and skip forced sign-in, but they don't care enough. There was a viral tweet once about somebody's grandma choking on a fishbone where YouTube responded telling them to buy YouTube Premium, so they're probably aware, but don't care enough. And they're implementing more measures like the forced sign-in for scraping prevention that happen to disproportionately affect public networks at restaurants and hotels. That's negligence.

Why's it so unreasonable?

There's a big difference between being a monopoly and negligent manslaughter.

Uploader choose to monetize vid, not Google. It's a per video option.

That's no longer true as of around 5 years ago. They'll show ads on any video they like.

https://support.google.com/youtube/answer/2475463?hl=en "YouTube may also place ads on videos in channels not in the YouTube Partner Program."

If you become eligible and join the YouTube partner program I believe there may be a toggle then, but for non partners it's completely up to YouTube.

And the forced sign-in of course never was controllable by creators.

Okay, but not really, right? once you upload a couple videos you become eligible to join the partner partner program. You just click yes that you've joined it and then you get the ability to select yes or or no for monetization. Certainly, WebMD is part of the partner program and is monetizing these videos on purpose, the same way that they have ads on the WebMD site. Having to sign in to use YouTube is not really that big of a bar. WebMD is making these choices, not YouTube.
