Possibly does. On occasion I read about German cities trying to do similar, but then reverting back to M$.

Most of the issues are around people not wanting to take time to get use to new software (happened at a job where they moved to GSuite) or the FOSS stuff not having a corporation that can be sued for loss of earnings (like crowd strike when they didn’t read only friday).

Still there is political support to not just use this as an angle to get M$ to lower their pricing.
