It's not sarcasm. It doesn't actually matter at all if Google Maps "tracks" you. But this pointless legislation decided it does and now people have to settle for surely inferior alternatives.
This is a guess, but I suspect the point had to do with data privacy. Maybe someone wrote legislation that prohibits public websites from hosting ads, or third party browser-tracking software. And google maps fits that.
In the parent comment, there's also this bit:
> but it is a lot cheaper than google maps
If true, this is an example of government regulations working as intended, and saving money.
