If this were indeed the average attitude, there wouldn't be this big of an outcry with regards to the move from fully open-source to source-available licenses (Mongo/ELK/Hashicorp/etc.)
wrong: source-available means you can look but you can't incorporate/change/copy-paste/get-inspired-by. "look at this wheel, learn but don't make your own". It's a travesty.
Don't you ever get inspired by reading good books? You can learn new tricks and apply them elsewhere, and it's much easier than actually contributing to a big open-source project.
Is that really how source-available works? I mean whos stopping me from screenshotting and using tesseract or some other OCR tool to get the actual no-bullshit source code
