Shareware is an interesting beast in the sense that it tends to be smaller scale and often open-source... and it's pretty common for creator/developers to ask for "donations." It also brings to mind paywalls where you can use this for free three times a day and beyond that you have to buy the "premium edition."

Which is different from freeware which is often riddled with bugs, stolen code, trojans and other annoyances nobody wants to deal with.
