IntoMobile is reporting that Nimbuzz had to drop another Instant Messaging platform, ICQ which is owned by AOL. Previously Nimbuzz dropped Skype under threat of legal action from the Skype attorneys.
I'm not surprised and would expect to see similar noise from Yahoo and Microsoft at some point in the future, not because I agree, but because it makes business sense to be able to control the Voice experience which is how they make some money, not off of the IM chat. No one cares about the chatting, its the minutes that matter. Then again, is either Yahoo or MSFT selling many minutes of calling through their messenger clients?
About the only company that likely won't yell about Open being the new closed is Google, who pretty much doesn't care how someone gets to Google, as long as they do, and with GoogleTalk and Voice, calls are mostly free anyway (except for International calls. One has to realize why companies like AOL, Yahoo and Microsoft all got more deeply into the IM space. It was to get people to SEARCH using their search tools. Well AOL with WebCrawler went nowhere fast. Yahoo, which invested initially in Google, has pretty much lost it's way, leaving really only MSFT's BING as a potential option to Google from the big brands. Even ASK.com is pretty much gone these days.
