The big voters have mostly said nothing from what I have seen... I have not seen posts by them... it's been a bunch of developers projecting what they think big voters want. I wish big voters actually communicated their thoughts more.
Right now sps in general is a crap show with everyone making assumptions and everyone seemingly having a different take on things... I think for a while sps just won't work and the return is gonna be top voted for a while.
Like you said everyone seems to have differing standards and theres for example a few people seemingly pushing the open source barrier when whales have not actually stated that is their own standard.
On our proposal we stated what our standard is.
Also if the example of milking steem is the video system then they milked steemit inc and their delegation. I'm not familiar with other projects but I haven't been around forever.
Some of them have said they d vote SW if it would turn opensource. You can check the last post about SteemWorld.
As I proposed in this post, an efficient channel to communicate with the whales (possibly through a Community) would be great to resolve that. Once again, I don't think that I'm pushing a barrier, I'm just writing about what I (and lots of others) honestly think is best, and readers are free to decide by themselves whether they agree or not.
I'm not targeting any project in particular and certainly not yours.
If a closed source project leaves Steem, decide to abandon the project or is suddenly unable to continue maintaining the project, all the previous funds used for development would result to nothing.
