It takes some doing, but you can live boot windows from a USB drive for those rare instances you need it. You can also just install it to a VM inside Linux (also not easy). But honestly these days the times where you'll NEED Windows are few and far between (and getting fewer and farther).
Not liking someone is not a good reason to root against decentralized platforms, IMO. The entire point of decentralization is that nobody gets to control the experience and who is/isn't allowed to participate.
There are many platforms in the Fediverse. The fact that the network can survive the collapse of one platform is a strength of decentralization. The Lemmy/mbin/piefed universe can only ever be exactly as big as we, the users, want it to be.
While Lemmy is still young we should establish a culture of politely, yet firmly ridiculing the weight of the mothers of users who don't de-clickbait headlines.
