Skype Classic has always been a favourite amongst many of Skype's users. Because of its ease of use, it has been adopted by the younger generation, by businesses, and by families wanting to contact loved ones overseas. It would be a shame to see it abandoned when so many people still prefer to use it over the more updated versions. There are many online discussions regarding Skype Classic's discontinuation, and it doesn't take long to see that many people hold very strong opinions on the topic. People like the way that Skype Classic works and dislike the lost features and the busy layout in the updated versions, to a point that rather than using the new version, they intend to find a different software entirely.
The solution to this issue would be to keep Skype Classic available to the public and give them a choice in the version that they use, rather than force them to update to the new version to continue using Skype.
