Gitlab is still the team that didn't notice that three of their three independent backup mechanisms had not been working for weeks to months. And while wholly cloning Github is legal, I started having serious doubts about their ethical instincts when they repeatedly tried to incite people against Github for cloning minor features.
Beyond that: it depends. I tend to believe large vendors are worse for privacy of generic consumers, because they have the scale where it pays off to sell data or do "big data" analysis. They are better for individual high-value targets because they have more. to lose, and less to win, relative to whatever they could expect by screwing you over. Protection against rogue employees is also something that happens in larger teams, if at all.
