I don't use Facebook, so in my case having a Facebook account in order to use the Quest is no different compared to having an Apple account to use an iPhone or a Sony account to use my Playstation. The concerns about losing access to your hardware and digital purchases on an account ban are valid, and I'd be in favor of regulations to prevent that kind of abuse, but I don't think those concerns should stop at Facebook. I have the same concerns with Valve being able to delete your Steam account, for example.
Other than that, the hardware is fantastic and solves a lot of problems I had with VR. It's light, relatively cheap, and needs no cables. Virtual Desktop is able to stream VR content from your PC wirelessy, and playing something like Alyx with no cables attached is eye-opening. In fact, Virtual Desktop is so good it made me change my mind about the future of cloud gaming (it works using similar principles, as it sends a video stream encoded in your PC to your headset, and the final result is very playable and crisp, to the point it's virtually indistinguishable from native; doing the same thing from a remote server adds latency to the mix, but not much).
The Quest fixes many of the problems I have with VR. The resolution is good enough (you can use a 1080p screen in VR at a reasonable distance with no perceived details lost), the price is good enough, it requires no PC (but you can use one if you have it, to play better version of games, or PCVR-exclusive top tier games), and it requires no cables.
The only thing missing from the VR camp at this moment IMHO is more AAA experiences. I've been spoiled by Alyx and I want more of that
