So you want to force someone with let's say 5 billion worth of exploration data into open to unlock the LYR bonus? I think in that case you can just as well remove the bonus.
Anything close to that value, that supporters of other powers could lose because of that? I have my doubts. There is no comparable relation between risk vs. gain.
Yes. If people want their cake, they must eat it. Open Only proponents should have to do their stuff in Open and not jump into PG/solo when it is convenient for them.
