Warranty...good,bad and the ugly

A few months ago I bought a Mac 402 new and had it shipped,Mac voided the warranty because of their policy on buying over the phone and having it shipped,I posted that info several months ago with lots of comments.I now see that there are several having issues with Wilson finishes and warranty stipulations..I had a Pass amp which was bought used over this site about 2 years ago,it developed an issue and even though I wasnt the original owner they still covered the warranty and even paid shipping on the repair(amp had about 6 months left on the original 3 year warranty)..Why dont all companies operate this way and just simply cover their gear from the time it was intially purchased reguardless of how many owners it has had,where it was purchased,who set it up etc etc..Seems rather silly and bad business...any ideas????
