The FreeBSD project in the meanwhile gets a little pressure off of their Xen paravirtualization efforts
That's not how it works. It's quite the opposite, actually -- the more people are using a system, the more money is available to fund further work on it.
Eventually Amazon changes something, since this is exploiting a not-officially-supported "feature", and the whole mess stops working.
Amazon is the most incredibly paranoid about not breaking existing systems of any company I've ever seen. (I sometimes wish they were less so, actually -- I've had to work around "this was fixed in Xen years ago but EC2 is running an old version for compatibility reasons" bugs.)
I don't think FreeBSD is big enough to get any sort of special treatment from Amazon, but I'm pretty sure Amazon wouldn't want to set a precedent for "Amazon broke my website".
