Lets look at what is going on here, it seems everyone but microsoft are saying buzzen should not use the chat ocx.
At the end of the day microsoft will decide what is what, if they were realy bothered i would think that they would have taken action long ago!
Microsoft are well aware of the ocx use and seem only concerned about any alterations or copyright removal from thier software, which is not happening to my knowledge.
I am sure if they leave the ocx on thier server they will add a disclaimer about it`s use.
Many users have the ocx installed on thier computers and microsoft would have to send down an update to disable remove it, by doing so they also have to allow users to see detail of any update and the option to refuse the sed update/ updates..
Due to the amount of users, they certainly would not or could not take legal enforcement to force removal or force an update on a users .
So at the end of the day, it is between microsoft and the company/persons involved, we can not say hey you are using that illegally, it is up to microsoft!
