Fair enough. Yet, is it unreasonable that a company investing in open source - in open source only - and doing all kind of work in the community, actively tries to engage with people that show interest? :) Unless of course they go after you with a gun to force you to buy something, but I think that's not the spirit of open source and freedom of choice, and making happy customers, in which the company operates ;)
