Open source is great in theory. And Can add more value given the same other variables.... the issue is that steem has a long long history of CRAPPY stupid little tools that get made quickly and then just kind of stop... and their code doesn't even seem to be used much. Sure there is some that continue on after the developer has their moment of fun then abandons the project or all of steem.... but if we're talking "value to steem"... then just being open source is a lackluster bar for making decisions.
I'd like to see more non-open source projects that actually do something awesome on steem and bring a ton of value to steem beyond just creating sub-par code that get's quickly forgotten and never actually helps the system.
We don't just need more crappy code on steem.... we need projects that have a plan and bring people to steem and use cases for the steem currency. There's so much more... making open source this barrier is soooo short sighted. It's developers thinking steem is gonna some how sky rocket just by a bit more extra code.
I see lots of people like @howo @anyx and maybe @dimitrydao talking about open source being this magic barrier and I just don't see it. Open source has value for sure... but making that a barrier is sooo short sighted.

But still interested in the discussion.
I haven't actually heard where the significant voters stand on these things.
