"through a modest donation of Dilithium"
MODEST ? With a daily cap of 8000 (9000 if you're a Lifetimer), you're looking at 16-18 days of non-stop grinding of Dilithium for a Tier 4 ship (150000 Dilithium). Might be easy for a max level character to obtain, but the time gating of it makes the grind meaningless.
The old Dilithium ships should've been changed to a "modest" amount of Energy Credits, with the formerly Zen ships replacing the Dilithium ships cost. Add to that, this change should've gone up to Tier 5 (not 4). Tier 6 is Endgame, so it's not like they'd be handing out top tier ships at low cost.
