Interesting perspective, but I don't think selling technology directly should be the requirement. I think a company is a "Tech Company" when the core product is technology produced by the company. I consider Facebook and Twitter to be tech companies, even though they don't sell technology directly. AirBnB and Uber have some decent open source contributions and have the ability to contribute back huge advances but probably won't focus as much on that until they're profitable.
