I believe yes, it's that easy. Zuck is breaking your feed posting ads and low quality retention content, you see only the most vocal discussions, people who post less often are not shown at all, and one day you realize your old FB which was more about connecting with others is just full of shit you have no intention of following at all. Sometimes your muscle memory wins so you open it once or twice to see what is going on, still same unpleasant experience, and then you quit.
