Thought on using guids for non-free stuff with trasferable skills to free stuff?

Example: Say if you watch a video or read a book on how to do x in Photoshop or Premiere and you're like "Hey, let's see if Gimp or Kdenlive can do that".

You get the idea, you just implement the idea in something else. I know there's plenty of guides on free tools, but that's not what the experts use and there's nothing wrong with somebody using a tool not used by experts like using Crayola Markers instead of Copics. Yes, a pro can make good work with Crayola because it's mostly the skill of the pro, but most pros are going to use Copics and one could transfer that mentality to another tool. Not to say I look down at Gimp, (or Crayola because I bought some) 2.10 looks fantastic, bit's easier to find pros that use Photoshop and DuckDuckGo how to do that step in Gimp or ask on stack exchange.
