I guess they probably could build a nice and fast website if it was up to them. But there's probably a lot more requirements than just that.
Things like https://twitter.com/wolfiechristl/status/1071473931784212480... are probably not decided on and implemented by the engineering team but are coming down as a requirement from the top. This is probably the case for a lot of other decisions that slow down the page ("We need this A/B test framework", "this needs to be hidden to increase retention",...)
