They are NO WAY near violating the spirit of GPL *or* the law. That statement is completely ignorant.
They *bought* Sistina for $31 million and fully open sourced GFS (Global File System).
They *bought* iPlanet Directory Server from Sun and open sourced it.
They *bought* iPlanet Certificate Server from Sun and open sourced it.
They *bought* Qumranet for around $107 million and are currently working to open source the virtual machine management software.
I haven't even started to list the projects that RedHat engineers directly contribute to in major ways. RedHat has been an *extremely* good citizen of the GPL because they put their *time* and *money* into GPL software. It has also payed off for them. RedHat is a Fortune 500 company now. They *only* thing they ask is that if you take their SRPMS and redistribute them, you remove their company trademarks. That is a completely reasonable request and is consistent with trademark law.
They could invest billions of dollars to setup their own infrastructure or switch to IP by carrier pigeon.
I expect that you will find out pretty quickly that you will want special bittorrent pigeons to separate the traffic from the ones carrying email and web.
