The bliss of inexperience :)

Services shut down all the time. I've been selling indie software for a bit more than a decade, and at least half a dozen services that I was using have either shut down, pivoted, or slowly became crappy enough that I had to move.

Of course, that doesn't mean that you should build everything yourself, that's not practical. But the stuff that I have built myself doesn't suddenly stop working.
