OS X Yosemite forces certain apps to be updated

I never felt the need to upgrade Final Cut Pro and Motion, as the old versions function just fine. But now in OS X Yosemite, Motion no longer works. Forcing me to spend $50 to upgrade to the newer version if I wish to continue to use it. This is an outrage, especially considering the old version of Final Cut Pro still functions just fine. One of the main reasons I didn't feel like upgrading, is that the newer apps are less functional. With the old Final Cut Studio suite of apps, you had tools such as "Soundtrack Pro" and "DVD Studio Pro" amongst others. The new suite of apps, which are all sold separately just include Final Cut Pro, Motion, and Compressor. It's not right of Apple to just disable certain apps.
