Given the earlier fallout with the twitter 3rd-party clients, and similar things going on on other "platforms" I think we need a new name for these services other than "platform" (since it is not stable, it's a bit of a misnomer) but more specific than "service".
I propose "network traps", "progress sinks" or "sucker tub". I don't know but I keep getting a recurring imagery when thinking of these situations as of someone building a house on a raft, which immediately capsizes, but the buoyancy of the house causes the raft to lift out of the water.
It's very clear that Twitter want to control every possible aspect of the monetisation of Twitter.
