With 20n, we had to tread more carefully. As monocasa implied, open source here means either code, or dna data. While code stays on the computing platform, dna's platform is every living entity.
Lets assume you could predict precisely what a piece of DNA will do -- we are not there yet, but will be at some time in the future. Are you advocating that all of that should be freely available? There are lots of benefits to open source and we understand a lot of it in the context of code, but IMHO, we will need to discuss more before we fully comprehend what it means to open source dna.
There are tons of opportunities, e.g., enabling bioproduction, and hopefully the beneficial nature of that (cheaper/carbon negative/environmentally-friendly) will be the leading argument in the conversation than anything else.
