Perhaps, but if they wanted any of their 6 million lines of COM-laden C++ to continue working into the future, they'd need those sort of people.
Assuming that a love of social interaction equates to programming skill would be a mistake, as would assuming that lack of love of social interactions equates to programming skill. The two sets of skills are unrelated, but in a company of people who don't enjoy socialising, forcing a social interaction is counterproductive.
To be fair, I find US forced company events like this way more unbearable than UK/European ones. In the US, the incessant combination of excessive alcohol with neurotic self-awareness gets you to another level of hell.
In another FAANG, the L7s were complaining that the level of office machinations that were occuring stateside was off the charts compared to the offices overseas.
UK afterwork pub culture should be under UNESCO cultural protection at this point, I'm always surprised it's lasted this long. One would have to admit it's fended off the decreasing consumption of alcohol in the new generation impressively even though they may despise the tradition.
I'm not familiar with European ones, but I agree that forced company events like this is the US are unbearable. I rejoiced once I hit a point in my career where I could safely skip attending them.
