Why free software has no warranty
No. Your impression is erroneous. Licenses of Free-as-in-swatantra Software enable you to provide warranty for a fee.
If there is warranty then we would get more support for our cause , what if free software is run on a life support system regards
Non free software does not provide any warranty even though you pay for it. Please go through the entire licenses of any non-free software license. These licenses do not permit third persons to accept the warranty liability for a fee.
I will try to explain this in a different way.
SITUATION I.
An example Non-free Software License reads :-

Here, the manufacturer accepts only such waranty the law does not permit him to refuse; you do not need a license to accept a liability imposed by the law. Third persons canot do anything about that.
Situation II

Re-read the lines with the | mark on the margin. Unlike non-free licenses, the copyright holders or third parties may, for a fee, accept warranty liability to th extent desired by the customer.
Whew!!! Sorry for the teal long quotes. I guess that most of you will not have access to the M$ EULA; so please bear with me.
In real life; in a real court, it is very difficult to pin down a liability for defective product if no payment (consideration) is made. If you do make payment for the product / service, it is next to impossible to avoid liability. So, on the issue of product liability issue, both Free and Non-free software are on equal footing; only that the users have the freedom of choosing the vendor they will pay for getting warranty support.
