Why do you seem them as a crutch/why do you see what they practice as "not meditation"?
For perspective, when trying meditation at first, I did it without the use of any technology- I read "Mindfulness in Plain English" and some other articles and books, and attempted meditating based on what I learned there (with mixed periods of success).
And then at some point later, I tried headspace to see what the hype was about. I found both paths helpful and effective- after all, the guided mediations in headspace largely just reflected the same things that the books had taught me. I don't have a headspace subscription and wouldn't get one, but I don't see it as significantly different than an audiobook version of some of the material I had read about in order to understand how to meditate. And maybe you could make the argument that people should just do that instead (listen to audiobooks, since the cost would be much lower). Do you see something fundamentally different?
