I was thinking about the comments about a "free trial". It seems to me the free trial model is not like a lot of the other free trial models. I never use a limited time trial offer. Usually, I don't want to buy the software so I am not going to download and use the trial model. Some of the "freeware" is mostly adware. Lightworks says this editor is free and always will be. I notice, too, the only suggestion that I should upgrade is the little red line of text at the bottom of the project selection window. However, it does bug me I don't have a pink shark.

Those things indicate a fairly high level of integrity to me.
My impression of the intent is they would like you to try the editor. I know when I tried it, I was overwhelmed by the intuitive nature of the editing process in the software. I have read the statements about the licensing issues. Even though I'm not in the industry, I am positive there are codecs out there that are strictly proprietary by design. So that part is a pipe dream.
All I have to do is accept that Lightworks is one tool in my workflow. This one tool is a good tool. I have some audio analysis tools. I don't want a full featured DAW to be part of my analysis software. In the same way, I don't expect my DAW to have an excellent analysis tool. I kind of look at Lwks in the same way. I turn to Lwks to use an excellent editor.
I do believe the plug--in and assistant application features have great potential. Let the people who develop excellent analysis tools or effects tools or colorizing tools or whatever make those tools. Then let Lightworks be the core of the workflow.
On the educational front, it may be heretical to say editing requires a fairly low level of technical knowledge. Understanding how the picture is packaged into data...

You get my point. You can take ffmpeg, ffmbc, Mencoder, etc. and make a library of presets and off you go. Presets is what you get when you can load "anything" into a program. I don't know how much educational value is in that.
Focusing on the business model. First you need a product that works. Then you have to get it into the hands of the consumers. The market includes a large proportion of casual users, like me. Here is the fork in the road. Either you can make a glitzy program with lots of one-size-fits-all features or you can focus on a narrower market, refine the product, and apply limited resources into producing a program whose hallmark is excellence. It's difficult to judge from the outside where in the timeline the development is.
That's my take right now.
