This is the big takeaway here. Companies thinking they are a monopoly, crippling their product to extract maximum short-term value (the MBA doctrine), and destroy the business long-term, because they now have an inferior product.
Less and less people are using facebook. Most (worldwide) never did in the first place. But an ugly man compensates for insecurity about his physical appearance by pretending he has more power than he does, despite him in reality having plenty of power to feel secure.
Facebook: you want to do something in an automated way? Enjoy your two day clickfest. Real life: yeah, I'm going to just use something else, and people coming of age will laugh about this legacy antiquated service.
Do you know how you get a fresh start without this process you found tedious? Put in a bunch of fake info into your profile, then just leave the account alone, forever. Then go somewhere else. Facebook has a large userbase. If you're not there for the other users, why in the world would you not use one of the hundred other similar services?
Now, as far as my personal opinion: facebook should lose the lawsuit. This extension is a script run by the user. There might be something that says the user has to click and can't run scripts, that the user agreed to. Facebook then has a case, against the user, and should start suing their users. Facebook has no standing against the people who wrote the script, but are not running it against facebook servers. I am free to write any piece of code, that does anything, as long as I don't have a contract with Facebook saying I won't. This is called freedom of speech, and a government does not have authority to make me stop. And a private company has no enforcement authority, because they're a company, not a government.
