According to Bre Pettis, nothing nada zip. "Nothing is changing with Thingiverse" is a direct tweet-quote. Move along now, nothing to see here (just like Dec last year).
And I'd hardly consider the people (Stratsys) who invented FDM (Fused Deposition Modelling, What our printer does) as being 'evil-megacorp'.. They just focused on the Commercial (where until a few years ago the market was) aspects rather than going for a home-brew piecemeal kit. Now that the two strategies are meeting in the middle, quick acquisition of MBI for their 'goodwill' (*cough*) and 'brand awareness' and voila, you can bother meddling with the home market now it potentially has value.
Particularly since Stratsys bought MBI not for the tech, not for any patents, but for the community and brand name. You really think they plan to flutter their $403 Million away given its all for the Community and Name??
