I can't say for other stakeholders, but I can say why I haven't voted for dapplr yet: they aren't starting opensource, but plan to migrate to it eventually, if I read their comments correctly. That just doesn't make sense to me (and I've seen several projects make similar claims, none of which I voted for).
If they were opensource, I would vote for them.
I respect that choice, and if they hadn't publicly/on chain promised to open source their app I wouldn't have voted either, but I can see why that's not enough for others to vote on now.
Still, my main point is, let's not create (financial) burdens for people to participate/add value to Hive. Although I do appreciate people having to prove their worth and thus our vote, I don't think financial burdens should be the (only) way to do so. A 'phase out' of irrelevant proposals over time (where the proposals still can receive votes but are simply 'below the line' for not receiving votes for x amount of weeks) would be a decent way of cleaning up mess.
