Proof that free plans don't attract the right users

Nice article! And I totally agree with the free users eating up support point. I was briefly part of the support team of another startup and I know it as a fact that there is nothing more agonizing than to see you falling short of time to support your paid clients. The thing is you can't give low priority to free users support requests since then they'll rant about your tool on social media and that's negative publicity for you.

In my opinion, I think no free plan should offer any support.

I think it's super attractive to new businesses to push their wares via a generous free plan. But in the end, unless you think word of mouth is going to take off. Validating your business model by charging is much more important.
