Yes, it's not really an attack just an annoyance done by those who are fearful of what SolidCoin represents. The new version (1.04) is going to blow away Bitcoin though as it has more features, will be faster and new developer stuff! Good times ahead.
Why doesn't BitCoin have mandatory updates like these? Even the really old clients still work.
Oh yes, their development goes: plan -> code -> test -> release.
Yours goes: hack code you don't fully understand -> release -> find bugs you should have noticed before releasing -> force mandatory update.
It's just a matter of time until someone finds a really nasty bug in one of the hacks you have made and uses it to either crash or rob the entire SolidCoin network.
I think i need some popcorn for this show. =)
