Finally taking this to these forums, and others, as I have tried to resolve the issue with Philgo68 without success.
Philgo68's Master Merchant addon borrows a number of features originally published in DataDaedra. Philgo68 claims that he borrowed the code from Millus Roster, an unpublished addon my friend Millus wrote (in his own words, using a number of things from DD, with my blessing). I myself have used code from Millus Roster, with Millus's blessing, and inclusion of Millus's license as he requires. However, among the numerous people Philgo68 thanks on MM's page, neither I nor Millus are mentioned, and his Master Merchant addon does not include Millus's license nor my own (which are identical).
To add insult to injury, many of the people Philgo68 thanks on Master Merchant's page frequently disparage me, and my addons, in guild and public channels. Those guilds promote Master Merchant, and either ignore or insult my own.
So far, I've documented the following features, and their lines of code, as lifted from DataDaedra without permission or credit:

I have worked tirelessly over the past year on my addons, and I am absolutely fed up with hearing people state that Master Merchant is "better" because it includes my features--features that were further developed beyond Millus Roster and published long before Master Merchant was released--and that DataDaedra is "incompatible" with Master Merchant because Philgo68 doesn't know how to include our (Millus's and my) LibGuildHistory, which we wrote specifically to solve any issues of compatibility with history addons. Quite frankly, I do not believe Philgo68 could have been completely unaware that they were in DataDaedra. I'm further infuriated that Philgo68 refuses to credit either me OR Millus, nor use the license we share.
I wouldn't be so irate had there been some acknowledgement of indebtedness on Philgo68's part in a timely fashion, nor if he wasn't thanking so many people who I've seen badmouthing me and my addons publicly. But now I want those borrowed features removed from Master Merchant, or Master Merchant removed from ESOUI altogether. Otherwise, what's he going to steal next so that people can say "Yeah, but MM has that too!"?
