Probably Yes!If I get your point correctly, the paid version is actually 100% the same thing except for adding a little touch of "Salt Bae"?
Joke aparts.....
It's sad to say but, giving something for free (especially sophisticated things) let it available to EVERYONE.
And of course that was your goal!
But in this EVERYONE you will get even curious, not skilled programmers, wannabe programmers that feel Bill Gates inside and so on.
All of these can lead you to a lot of bad comments or other.
Making something for payment should keep away the
"Not really interested persons"
and the
"I don't know what this is but I take anyway because it's free."
This rule apply even when you want to sell something.
Even if you want to give it away for free or fit a very low price, initially make it with a bit higher price.
This will keep away the FOR FREE I GET IT ANYWAY and will make you to be contacted only by the real interested ones.
Then you can lower the price or give it for free to who will call you KNOWING WHY they called you.
Sorry for the long post.
