Celtx used to be a great Foss desktop screenwriting application, based on Firefox. Eventually they tried to go web based, and I had to move over to the closed sourced, industry standard, final draft when my work started getting produced.
Now there are a thousand open source screenwriting tools, and not one that I like.
You can confidently say that this is fine for most consumers today. There really isn't a great argument that this will serve most consumers well for the next 3 to 5 years.
It's ok if well informed consumers are fine with a compromise for their use case.
Misrepresenting the product category, and misleading less informed consumers to believe that it's not a second rate product in the current generation is deeply anti-consumer.
