Gridcoin's voting system favours rich people (be it money-wise or magnitude-wise, both types are rich) and we can't change something without the "whales" accepting it also :-(
look for example at this ongoing discussion for nearly 1 year here (most whales would be against the idea, let's see if we come to a compromise)
I'm not sure what makes you think "most whales would be against the idea" -- a number of them have come out in support of the idea because it will ultimately make their holdings more valuable, not less. I think there's a very good chance that a fixed stake reward will be in place within the next year. And it's a very good sign that Rob himself has come out in favor of the idea.
As for your point about the top 50 addresses owning 48% of all GRC, I'm not sure why you think this is so noteworthy. That's pretty much true for every cryptocurrency out there (it would be interesting to know for which currencies that is NOT true) and many of them are much more concentrated. Bitcoin itself is still concentrated in the top 1000 addresses and it's been around significantly longer than the rest; it will take time for holdings to dilute. I don't see a problem here.
Talks are talks, the change (if it ever comes), this I will believe. Talks are going on in that bug thread for 1 year, in the meantime the "gap" between the few "above" and others still increases...
Yes, the concentration of the most portion to a few only is common everywhere (be it virtual or real world).
I see a problem with it, especially when you know of the situations how it came to this concentration also...

If you want to look at the power, look at this poll outcome:
The foundation wallet holds currently 22.4 million GRC (5.65% of all coins) and 4 months ago it was decided that we raise the "minimum vote weight required", meaning stuff like:
