Great, now you have one less company selling your data out of thousands. And remember that FB will still retain your profile forever and continue build on it via shadow profile - from everyone you know, and probably from bartering data with other companies you still use. From Google/Apple powering your OS, from Cell operator collecting info with baseband chip, thousands of them. I'm not saying FB is good, I just say that this fight is already lost, delete FB account or not.
