I've had some working experience with SAP. If you use their latest and greatest, it's not as painfully bad as people think it is. Large part of SAP will be in-house customization (or you pay SAP to do that), so that is a very mixed bag. The other part is; SAP supports things forever. You can run their old buggy DB from 2003 in 2021 with paid support. Bug-for-bug compatible on Windows Server 2019 probably too. That has a lot of value for a lot of SAP customers. I would also remind that SAP (and DTAG) built the german corona tracing app, which was delivery in about 2 months, open source under Apache2.0 and very privacy aware. And well within budget no less.
