Ex-Meta employee here. I worked at reality labs, perhaps in other orgs the situation is different.
At Meta we did "fix-it weeks", more or less every quarter. At the beginning I was thrilled: leadership that actually cares about fixing bugs!
Then reality hit: it's the worst possible decision for code and software quality. Basically this turned into: you are allowed to land all the possible crap you want. Then you have one week to "fix all the bugs". Guess what: most of the time we couldn't even fix a single bug because we were drown in tech debt.
