It is a concern alright!
$520 million debt of Gibson and repayments have to be met.
It is plausible they do go bankrupt.
If that means CW will be sold off for peanuts under receivership might be a good thing for users.
Or Gibson ends all contracts with CW by closing the shop and concludes business and maybe sell it off for peanuts before they go under.
That they are concentrating on consumer electronics is where more money is at and they might begin to be able to pay their debt.
More then likely the servers will stay up while CW software is still relevant.
If it takes too long and CW is long dormant. It would be irrelevant if the servers are switched off.
Logically, it is 2:1 that it will be sold off.
