This 100%. I strongly embraced both platforms early on, but their nature has changed in so many ways, and the balance of benefit to me vs. benefit to the vendor has tilted way too far towards benefiting the vendor. At this point I've blocked all FB-related domains for my computers (Pi-hole) and use other methods to keep in touch with family and friends. The same thing is happening with Twitter. Every time I view the web interface (or official mobile app), I'm disgusted by how exploitative and user-hostile its current iteration is. Luckily I normally use a 3rd-party mobile client which retains some of the aspects that made the platform appealing (permanently-linear timeline, no ads). The disparity is night and day. Unfortunately I'm "forced" to use the official clients from time to time as the 3rd party one is no longer being updated and lacks some features (for example some videos simply don't play). Still, at least it keeps the service mostly-usable. Regardless, I'm using Mastodon more and more as it's what Twitter "was" and can never be again.
