Today I read that QlikSense desktop will no longer available for download and use (as well as existing installations) from June 2020. 

Rumour or fact ?

Why do this ? Besides profiteering ? Surely there are other ways to encourage early adopters ? Forcing people to Qlik SaaS offering is not a great option as it does not support much in the way of extensions and of course locks out 3rd party extension provides such as VizLib which I use when prototyping before migrating to a server.
