just to illustrate how ridiculous these claims are, I created this little parody:
"It's my job to assist in the destruction of the Linux operating system. Currently we are researching various methods that will be used to attack free software in the near future. Previous attacks have resulted in usage drops, but we will not be content until Linux has been driven completely underground to a very small amount of fanatics with no chance of taking off into the main stream software world."
"I want Linux to be destroyed. It's not personal, this is just a requirement of the company I work for."
The problem with your parody is that there is evidence supporting it. Microsoft extended support for Windows XP after netbooks threatened to prove that GNU/Linux is more versatile, yet still usable by the average person. As a result of Microsoft pressure, netbooks moved from Solid-State disks to spinning disks in order to have enough space to install Windows XP. This results in a slower, more power hungry computer that is simply less functional, other than in storage capablility.
Microsoft also
charges manufacturers approximately the same license fees for both Windows Mobile and Android handsets. At the same time, Microsoft limits what features the Android phones are allowed to have. You can thank software patents for this situation.
TL;DR: Your parody does nothing to prove one way or another whether this annonymous person is telling the truth.
