I *love* your program. It is simply wonderful, simple, elegant and useful.
The problem is garbage like Open Candy and IronSource. These things cause incalculable wastes of time and problems, especially for novice users. I can not and will not ever recommend a program/app which is associated with distribution of browser search bars, adware, ransomware (in effect), and misleading trash like those addon programs. Sure, I can get around the obstacles but I shouldn't have to. IronSource's only true purpose is to place unwanted and hard to remove (and potentially hazardous) junk on someone's computer without their complete understanding of what it is doing. See for example:
The obvious answer is to provide two clearly delineated downloads. The first with the addon program, if you must, including a very clear explanation of all the problems it can cause and a careful step by step set of instructions on how to bypass it. The second, a download requiring a modest payment via PayPal or even a donation if you prefer but without the poop.
In any case, use of software which installs unknown and poorly defined addons to the end user's computer is unconscionable. You should stop doing it immediately. It detracts greatly from your otherwise excellent software. It has caused me to search for a substitute because until you rid yourself of these scourges, I simply don't trust you. Use of Open Candy and IronSource is a horrible, despicable business model. It seems Open Candy has finally been stopped and is out of business and I can only hope the scammer-helpers at IronSource will soon follow.
Edited to add: OK, I see one can download a version without IronSource. That's fine but it's not properly advertised... you have to read the FAQ and it's buried deep inside those. It should be at least in the EULA. Better yet, the clean version should be the default. And I say again, many end users including me, would be delighted to pay a moderate fee, say $25, for a copy or we'd be happy to make PayPal donations. Why don't you do that?
