NXT is a social experiment as its founders like to say, devs give forgers a choice, so that forgers can exercise their right to vote with their forging power. That's the reason for this patched release. This goes to show the spirit of forgers and what they stand for. If they weren't offered a choice, it would be unknown what forgers stand for, and whether they truely support ideas of crypto currency. NXT forgers proved they do. You can keep trying to twist it as if it's not in NXT favor, but for all unbiased people it's clear to see what it's all about. But trolls gonna troll, it's their life.
So why don't they introduce this as a permanent feature? Give forgers the option to whitelist or blacklist every single transaction at will.
Maybe with a nice thumbs up button.

Do you know why? Because this would be the shittiest of all alt-coins...
Actually forgers can do that on their own, NXT is open source, just like in Bitcoin miners can do that.
They can modify the software to include or not include txs.
If 51% (or 90% soon when Transparent Forging is enabled) of forging/mining power agrees to use the same modified software, then an alternative longer chain can be formed. That's the beauty of crypto currencies

and that's basics of crypto currencies too

I agree. That's why the community turned down that unacceptable patch.
Still i have some news that might shock you. Even in open source programs you need developers. Developers to make them and maintain them.
And the fate of crypto-currencies is pretty much tied with the reputation and the actions of its developers.
