I agree, they do need to do a better job of fixing the big issues. The performance update is not a big issue. Technically it's not even an issue, because as Cpayne pointed out it usually doesn't release until around F1's summer break so if it arrives in the next patch or two it really isn't late.
they released two tiny patches in a row.
A: Just because you didn't like what was in them, doesn't mean they were "tiny", for some people the fixes were quite significant.
B: They also released those patches in back to back weeks, when normally the patch cadence has been every other week
