ABS Why? Why? Why?

Hello BMW municipality! I recently read a test report from a current BMW motorcycle, don’t ask me which one. What immediately tells me in the report that the bike ABS had! ABS! Both wheels should even be braked with the same brake grip or foot brake with ABS. Since I have never ridden a motorcycle, I don’t know how to classify it. In my opinion, a motorcycle without ABS is so dangerous with a full brake, since if possible you use both brakes However, it should avoid blocking both brakes as much as possible. (whereby blocking the VR brake is probably the worst… 🙂 To my question, ABS is actually a huge enrichment when riding a motorcycle or is everything no problem with a Volbrake without ABS, if you are not a beginner? However, if ABS is really useful, why the hell isn’t it installed in every bike, motorbikes aren’t cheap as well?! S already offer or at least will be offered in the near future? Perhaps my question is too banal, but in this case I would like to take a look, as I 1. do not ride a motorcycle and 2. because I have found nothing despite forum search. I would be happy about answers. Mfg SicAngel
