Building a Linux distribution requires a fair amount of infrastructure, and that's something that's pretty different from distro to distro (and not all make all the necessary tooling public). Changing to a different base distro would most likely require a significant rework, and may be more than someone, especially someone who has mastered the intricacies of one distro's tooling, wants to do.
You have to register as a company before you are allowed to offer taxi services. It's illegal for individuals to provide taxi services. This is to protect customers from malicious taxi services which are unregulated, unsafe, extremely expensive, etc.
Hi. I think you are confused.
Air India crashes/fatalities:
* Air India Flight 101 CONTROLLED FLIGHT INTO TERRAIN -- https://en.wikipedia.org/wiki/...
* Air India Flight 855 PILOT ERROR -- https://en.wikipedia.org/wiki/...
What does the word perfect mean to you? Those are crashes. People died.
We can even add:
* Air India Flight 182 BOMBING -- https://en.wikipedia.org/wiki/...
Though that's also on the staff at the airport doing security screenings.
