It is exactly the strategy of all platforms - they get greedy to the point of screwing over their own customers. I've lost count of number of times I've seen a platform get popular and then expand to offer the same services as its customers, often even undercutting market rates.

Just wait till they offer "Developer Certification" so you have to pay them to get a shiny little badge and a certificate while they go around saying no badge = you're shit.
