Drew explicitly doesn't mention his own project/company, so I will:
For $20 a YEAR, you can be an 'Amateur Hacker' level supporter of his FULLY FLOSS platform.
If you believe in 'voting with your wallet', that's an excellent way to support and promote FLOSS alternatives.
There are also other plans for $50 or $100 although it currently doesn't provide extra features.
