The people never give up their liberties but under some delusion.
-- Edmund Burke
They who can give up essential liberty to obtain a little temporary
safety, deserve neither liberty nor safety. -- Benjamin Franklin
"But it works" is a common rebuttal when we recommend people to reject non-Free Software. It is quite a short-sighted one.
It might even seem like it's convenient and costs less in the short term, but in the long run, the dependence will cost you. And that's exactly why it's imposed on you!
It doesn't matter how much you think you can trust the company that provides you with the software. Trust is supposed to be mutual. If they refuse to let you help yourself, not trusting you to remain their customers, how can you tell they're not making you worse off today, or planning to do so in the future?
Why would you entrust your future wellfare to someone who won't let you stand on your own even today?
