I would be quite upset if the car manufacturer attached locks to the hood of my car without warning me. I might be considerably less upset if there were both "cars with locks on their hoods" and "regular cars without locks on their hoods" and if I was offered the choice between them. It's quite possible to support the choice between FOSS and commercial software, and think that FOSS is a great thing for people to develop, without deciding that people whole build closed-source software are "immoral". Don't like it? Don't buy it. I know this is a bit disingenuous and there are corner cases where it's hard to avoid closed-source. There are even a few cases where no amount of consumer choice (even, say, someone who avoids smartphones and 'cool gadgets') will allow you to escape closed source (e.g. government services available as closed-source software only or working only on platforms where you have to use closed source). The point still stands, broadly.
