Dunno if it was incompetence or malice, but the straw that finally broke me over to Linux permanently was a privacy setting in Windows that appeared to work until you re-entered the menu and it wouldn't persist. In my time at YouTube though, privacy issues were an immediately fireable offense, and even when my role required data, use was gated and then still logged, and misuse was handled. That's an n=1 apples-to-oranges data point, but I personally trust Google a bit more than MS with my data.
