1) Not a single poll that I've seen yet to reaches even 500 points, but, yea, the majority. most people don't care to go out of their way to defend this system, most people frankly do not care. I know that there are many concerns, they're being brought to Mojang, and are at the very least slowly reacting on it.
2) Many western governments have a "regulate your platforms or we'll force you to regulate them" message going out, that's why many platforms over the past few years have been rolling out and improving moderation tools, Minecraft is just the next "victim"
3) The current environment allows players to play on servers, all of which have agreed to the EULA, and expected to deal with stuff applicable to their server; i.e. ensuring that they follow regulations, GDPR, data protection, COPPA, reporting illegal activities, etc, etc; It feels like we hardly go a year without somebody somewhat big in the community being exposed for being a creep, and those are just what we know, mojang is wanting to release tools to deal with this mess, and their own legal responsibility to moderate their platform. "but, we run the servers!", doesn't absolve mojang of their own legal duties here.
4) the "just play elsewhere!" is a shitty thing to say when you can pretty much follow anybody around, I've heard a few stories of females within my friend group whom have had the odd person try to follow them around servers, I know that there's been several tools which will pretty much let you follow people around a good % of servers on server lists, or platforms like enjin which where heavily used by the community, "just go elsewhere" is a pretty shitty thing to say to somebody who's being targeted by harassment and grooming.
