OR you choose to delegate the burden of running and maintaining this software to someone that will do it in a more cost-effective way than you ever could.
Or could close their "beta" you were depending on without notice, could lose your data, could leak it, could give unexplainable corrupt results and leave you looking like a fraud, etc.
There are a lot of opportunities to trade off short term ease for tail risk, and thats a bit hazardous. RMS would probably argue that while you should have the freedom to do such a thing, you really shouldn't both because of the harms to you not being justified if you don't overemphasize the near term, and also because of systemic effects like losing solidarity with other people who would prefer to make another decision().
[e.g. many people who choose to run their own small mail filters find them regularly invisibly black holded by major mail services due to overactive spamfiltering.]

I don't have to use SaaS to have these results. I've seen in-house efforts with the same risks. The difference, in my mind, is that with SaaS, the provider has some significant incentives to do a good job. The software is their specialty, and the developer will lose money if you stop using it because their software ends up costing you money. There's much less risk of internal company politics saddling you with a useless or dangerous system. On the contrary, I've seen "self-hosted" company projects promised in response to proposals to use SaaS, and they were usually promised to achieve some political goal rather than being a serious attempt to compete. Because it's an internal project which doesn't generate revenue, it's very easy for the company to promise something and then not deliver, as there's no money tied to it.
Having seen this multiple times, I'm much more inclined to use SaaS. Tail risks don't cost nearly as much money over the mid term as the risk of company politics derailing an otherwise laudable goal.
