For your question, though: I don't think it's "your fault" that anything bad happens to you. It's obvious that the problem lies with the company you're working with–it's just that this kind of bad behavior is unlikely to change, so you unfortunately need to take it into account when dealing with them. If you had asked me earlier I probably would have said something like "be wary: the management of today might not be the management of tomorrow, or they may shift priorities, or they might just straight up being lying to you". If all goes well, that's awesome, but I still think it's important to consider these things.
By way of example, one of the apps I work on has effectively gotten approval from senior management–essentially, what it does is "legitimate" and "within the rules". What this means we have reduced our investments in thinking about scenarios where it gets removed from sale, but continue to maintain our ability to deploy elsewhere even if it is little-used right now.
