Yep, but some surprise page isn't going to get a lot of people spending money with Skype. but will get a percentage of people looking for Skype alternatives. Based on my experience, the conversation rate would probably earn them $1 per 250,000 annoying pages.
If I was marketing Skype, I would be trying to increase the user base, try make and sell it as the only phone that people need. Sell a home phone replacement, that easily connects to a Skype account once plugged in to the Internet. - if there's isn't one already.
If users are then not using other phones, they would be a lot more willing to part with cash for Skype.
Our kids use it the most to video chat with their friends. It is free, unless you want to be able to call real phone numbers. And it used to be very secure method of communicating, but I think the government recently and quietly got skype/Microsoft to start keeping call logs.
Skype, though owned by MS, is still an EU (Luxembourg) company so is legally required to keep call logs for at least six months (the law in Luxembourg may require more). This is the same (EU) law that requires ISPs, telecoms companies and other service providers to keep web browsing, email, IM, SMS etc. logs for the same period.
