I've been contacted too. I'm not planning on removing my article either. It feels like a bluff. I find it odd that their first course of action is to threaten legal action. Not exactly the way to win friends and influence people. If they really wanted to get on the right side of this they would acknowledge what they did and then approach people with an apology. Meh.
I've known Brandon for close to 10 years. I'll also state that Brandon and his team are some of the most competent programmers I know. He was easily one of the top developers of add-ons for ExpressionEngine before starting Craft. His dedication and customer service are top notch and he, in a very jobs-ian way, seems to know what developers need before they even ask for it.
Craft will be around for a long time. Open Source projects see higher adoption rates because hosting companies have 1-click installers for them. But if you look at high quality, high traffic sites the playing field is much more evenly spread.
Anyway, buy with confidence. Brandon doesn't know I am posting this. He did not ask for this endorsement. But I love what he is doing and would easily recommend it to anyone looking for a flexible system that is easy for clients to use
Absolutely amazing. Love these. Even showed them to my oldest son as he likes to draw.
