When you post here you are not addressing Adobe. This is a user forum site you are addressing Photoshop users like yourself. We have nothing to do with Adobe Program development or any say is what Adobe releases or changes the make of fix Adobe code. All we can do is help each other out with using Photoshop and use Adobe feedback site to report Bugs and make suggestions to Adobe.
If you had search this forum instead of trying to rant on Adobe you would have found download links for old Photoshop CC versions from CS6 to cc 2019. Photoshop 2020 and 2021 are installable through the Creative Cloud Desktop Application.
