For what it's worth, I opted to wait until I had my first issue with PIA after the buyout to switch and it just never really happened. I've remained on PIA for my sea-sailing needs, and still haven't had an ISP email or other problem with them, other than the client being a little janky on occasion.
I'm not an active advocate or anything, but my experience is that they're still good enough, even years after the acquisition. Perhaps they're using the data for something behind the scenes, but it's cheap and keeps my ISP off my back. I'd at least still consider it in the "good enough for this purpose" category.
