The way I see this, Xecuter's market is everyone above FW 3.0.0 or that is looking for piracy. They are going to charge money because they know that is the majority.
qlutoo & co's market is everyone 3.0.0 and below. This is better for them, actually. Everybody that wants piracy is going to be in the Xecuter community, which in turn will be the most cancerous community (because of "free games") while their community will be people who are primarily interested in homebrew and the development of it.
Of course, qlutoo & co's market will go down in numbers even after Xecuter's release, and they eventually might just switch over themselves if it is reliable enough for their own needs.
There should be no jealousy. All I see is the majority of users being those who updated, calling out qlutoo & co because they didn't support them, which they couldn't have done because of exploit limitations; and the minority who didn't update calling out Team Xecuter for stealing work, which they couldn't do in a 5 day timeframe.
