I like to install Gnu Linux distros ,& help set things up on people's computers for optional donations

I want to do this for the least well off to the most well off individuals and businesses.

I tried to find an answer to a question about it being optional..

I like it optional for two reasons

1,it helps those not so well off ,which is good for everyone. Because Linux is better at privacy and security. It just has some minor problems for those who like gaming,which can be solved with a little effort.

2,I think that it being optional means that when one does choose to make a donation,it's not about the services rendered because it was optional.. it's a real donation,so I shouldn't have to do paperwork.. losing money on taxes is not what bothers me ,it's having to do more work..
