Does adobe distribute acrobat reader for Linux platforms?

First things first - If I got it right, the Linux folks might like adobe alternatives like GIMP (instead of Photoshop) etc to work with images/pdf/videos on Linux. So they might never miss adobe products on Linux. But what brings me to this question is - i found a article which describes on: How to Install Adobe Acrobat Reader on Ubuntu 20.04 Focal Fossa Linux I was surprised, because as per my understanding, none of adobe products are available for linux platforms (correct me if I am wrong ). Then I though Acrobat Reader might be an exception and checked on adobe site. My finding is as captured on the screenshot. --> No, there is no Linux Version of acrobat reader on adobe site. 1) I want to understand how ftp://ftp.adobe.com/pub/adobe/reader/unix/9.x/9.5.5/enu/AdbeRdr9.5.5-1_i386linux_enu.deb exists when adobe does not show it on their website (ok even unix version is not listed on there website). 2) Like Acrobat Reader, are there any other products like Flash etc that can obtained through FTP.
