Facebook is my e-commerce business' main avenue of customer acquisition. It wouldn't make any sense to avoid using something that is clearly a profoundly valuable asset because something could go wrong at some point. Even if they shut off my access tomorrow, I've still gained the thousands of customers who I acquired - they've already generated a profit for me, and I can keep reaching out to them via marketing emails to make more sales.

Same thing with Amazon - it's been one of the easiest ways to sell. I listed my stuff, spent a little on ads, and things have just been slowly and steadily up and to the right since then. Even if they kicked me off tomorrow, I've still made good money in a very time-efficient manner.

It's one thing to say you should get Fastmail instead of Gmail, but to just say you should avoid using services that are valuable for your business because you might lose access later is cutting off your nose to spite your face.
