Also, in regards to gp, saying .com is for all commercial companies is the equivalent of saying all commercial companies have to be in business with Verisign.
I'd be for abolising .com (and other gtlds) too.
Also, if you think about what the world might be like 50 years from now, ".com" and ".org" might be remnants of the past we remember fondly. They will likely become less important on their own.
The only real problem as far as I see it with cctlds is that it reinforces the notion that you must pick a country to be subservient to, but you aren't really escaping that by using gtlds..
The fact single companies manage TLDs doesn't factor into my thought process on how we should manage the TLD namespace.
It sounds like your problem is really with Verisign et al., perhaps the fight you're looking for is how individual gTLDs are managed in the first place, not assuming that part of the model is fixed and exploding the namespace in some bizarro business fairness.
As far as I am concerned I see no reason not to have thousands or millions of top level domains.
I am a believer that with ample time and more options we will see the false assumption that everything is a .com become less widespread. (Although this belief is largely based on wishful thinking, I will admit)
