I for one think the posts are an example unprofessional practices on the part of F2Pool, and are of topical interest to miners considering using the pool. I hope history isn't whitewashed through their removal.
Wait, the agreement was first signed "Adam Back, Blockstream" and then reverted to "Adam Back, Individual" (and finally back to "Adam Back, Blockstream"), and this is somehow F2Pool acting unprofessionally by calling them out?
My take is that people are catching on to Blockstream/Core's semantic trickery, and it's beginning to backfire in their faces.
