Do you really not see the problem with suggesting people switch careers every time an overbearing corporation starts exerting excessive control over their industry?
Facebook provides services that people want to use, like Login, or that provides real value better than the competitors (Marketplace).
Complaining that you “have” to use Marketplace because things sell faster on it is totally bizarre.
That's almost always true of monopolistic practices, so I don't see your point.

If things can't be sold quickly, they often can't be sold at all. There's no place to store this stuff if it can't be sold fairly quickly, as the properties are usually being sold.
Maybe you're rich enough to turn down money, but a lot of people "have to" work for money.
What excessive control or monopolistic practice did Facebook exert in order to help you sell your stuff faster?
Being better at something because you have a lot of users and a halfway decent UI isn't anti-competitive.
Contrast this, for example, with Intel paying competitors not to also sell AMD chips, or Google listing their own inferior products higher in organic Search results.
They aren't helping sell things faster. They're forcing me to use their platform if I want to sell things slightly slower to how I used to sell things on Craigslist. It's faster to sell on Facebook now, but it's not as fast as it used to be on Craigslist.

They aren't better. If anything, their tooling is inferior to Craigslist's--it's harder to find the things you want on Facebook, and Facebook's seller tools are rudimentary. Facebook has a larger user base because buyers have moved over to Facebook, but the idea that this is an improved experience for anyone is flat wrong. The migration is because Facebook is using their other services to direct people into their marketplace, not because they provide a better marketplace.
