They will not get such contracts anyway, and those that do get them generally deliver equipment that is a little more sturdy. At its price, of course.
Yeap, I agree. In my country at least, it is certain that the job will go to the company with the worst price and the most kickbacks to the politicians and other public sector parasites that will push for them (ignoring of course better and cheaper solutions).
It is just a different world. A world that requires certifications, guarantees, physical quality, support, etc etc.
The reason that the equipment that is compliant with that is so much more expensive is that it costs money to do all that.
MikroTik WiFi is just for hobbyist and wannabe 1-man WISP, and maybe some small office usage in low-income countries.
Projects like municpal WiFi are another market segment. You don't want MikroTik to be in there or it will become just as expensive as the big guys.
