The same question could be asked for any SaaS provider. I seriously do not understand the constant circle jerk over SaaS. How many companies going tits up does it take before someone says "hmm maybe if I control it I have less risk"
Of course the same question could be asked of any SaaS provider, and I'm sure it is in the appropriate context. However, 23andwalnut did choose to go the self-hosted route so I think my question about why he chose to go the self-hosted route is completely valid and not at all a circle jerk over SaaS. You seem incredibly defensive over a simple question.
Your question implies that SaaS is the assumed/"normal"/"natural" way to go when developing software, which is basically the circle jerk I was referring to - if it isn't a format locked system your customers have 0 control over or visibility into, it isn't worth doing?
