In this case it is rather obvious. From what I could see on quickly checking their homepage the software they advertise is Windows only there is no Linux version available for download. Ask Ubuntu is defintely not the right place to post. The tech support team of that software will know that.

If they still do place their advertisments here I consider this as spam without the slightest doubt, even if there was a free version available.

For my view on Open Source projects or other Linux software also see these related posts:

• Should I keep an eye on spam-like answers about free software? Or why do people spam-promote free software?
• Is it good style to downvote developers who announce their projects?

In this case it is rather obvious. From what I could see on quickly checking their homepage their primary download directs to Windows and from my Windows office machine I could not find any downloads for Linux. Only on searching deeper into their help pages I found a guide on how to run this Java application on Linux. The advertising posts give no help whatsoever on how to download, install and run their software on Ubuntu.

Any application should be designed to be easily installed through our package manager and and it should run on Ubuntu, otherwise Ask Ubuntu would not be the right place to post. The tech support team of that software will know that.

If they still do place their advertisments for a closed source application here I consider this as spam without doubt, even if there was a free version available.
