Can someone who's worked in an org this large help me understand how this happens? They surely do testing against major browsers and saw the performance issues before releasing. Is there really someone who gave the green light?

As someone who has worked in and with large orgs, the better question is "why does this always happen?". In large organizations "ownership" of a product becomes more nebulous from a product and code standpoint due to churn and a focus on short-sighted goals.

If you put a lot of momentum behind a product with that mentality you get features piled on tech debt, no one gets enthusiastic about paying that down because it was done by some prior team you have no understanding of and it gets in the way of what management wants, which is more features so they can get bonuses.

Speaking up about it gets you shouted down and thrown on a performance improvement plan because you aren't aligned with your capitalist masters.

That the optimization pressure imposed by "capitalist masters" can lead to perverse outcomes does not imply that the optimization pressure imposed by communist ones doesn't, surely?

For instance, the GP could be a proponent of self-management, and the statement would be coherent (an indictment of leaders within capitalism) without supposing anything about communism.
