Current situation where blocks are getting full from artificial 1MB cap:
Attacker: large miners like f2pool
Attack: spam network from one of its wallets to another. Drive up overall fees of regular users.
Success: 100%

You just described a version of the "denial of service" attack already mentioned.

Not sure i follow.

Right now we could be having a situation where f2pool is spamming the network with TX's paid to itself which raises everyone's fees of which they will mine 21%of the time in proportion to their current hashrate. Yes, they lose 79% of the fees used to do this but overall it might work out in their favor.
