Making it impossible for me to even see my own profile or message with people I previously hosted is exactly what I call "aggressive". It's not about the cost, it's about what exactly is being restricted. They literally took content that I created (MY profile) and are asking me to pay for it. A sane monetising approach would be to charge for sending new requests, for example.

100% this. They took away all the (often very personal) reviews that is part of my account, and forced me to pay for access to them.
