Network Solutions has always been the lowest of the low in my eyes except for a few rare, craptastic exceptions. I've never used them, but some acquaintances have and it's been a real horror show to watch (and try to help them deal with NS).
They charge premium rates for subpar offerings with tons of hidden charges. I remember researching them relatively recently for someone who was asking me about their current, basic pricing structure on stuff and a lot was hidden from the website.
You could tell they just hoped that people would sign up, get locked in and then nickel and dime them to death for basic services. Not even Godaddy stoops that low to reel in uneducated customers (as bad) and that's really saying something.
I hope this latest scumbag maneuver puts them out of business for good.
