The fair criticism of Stallman is that he is absolutist, idealist, extreme, and uncompromising. Whether those things are positive or negative is really up to how you feel about the relative importance of Free Software vs. other issues.
I am personally willing to compromise quite a bit on the free software issues for other gains, but I think the "right to read" consideration for consuming materials other than code are less ok for compromise. I use and enjoy facebook, but look at their motivations and culture as a company before deciding how much to trust them.
I trust the people at facebook a lot more than a lot of companies, so one of my main concerns with facebook is that third parties might purchase, steal, or compel access to their data to use against users (e.g. Corrupt governments).
