I'd also like to point out that, even though, Google has very deep pockets they still made some changes to the free version's import capabilities removing DWG/DXF import in order IMO to strongly influence a move to the paid version for the professional users. Free or very low cost can devalue a product. While I really haven't much money I still don't like to see small companies going out of business due to products priced too low. MOI is already several hundred dollars cheaper than its peers. And frankly as I travel around the WWW I notice that MOI is more than popular enough with the crowd that doesn't pay for software. Exposure isn't the problem.
