There is more going on with Russian intake design than you seem to be aware of.
While your reaction is natural, you would find it wrong indeed, if you would do some research into an alternative approach minimizing radar reflection from engine intakes that has been pioneered by the Russians. In fact there may be elements in there that could be copied by US eventually.
Not stealthy. The Russians themselves say this. They “chose” not to have stealth (it was too expensive).
These are not designed to go up against Raptors.
