Again, I know the difference. You have a problem seeing through only one lens however. Stop talking to me as you are just like a puppy sniffing my butt for the last couple days.
Show a basic understanding of what people are talking about and maybe you won’t get talked down to.
You still don’t seem to grasp that all this add on is doing is parsing and send chat messages. Any groups or information it provides is available to everyone regardless of whether they are themselves using the add on or not. Hence no one is being excluded from or missing anything.
Man… this upsets and scares me! This and Gear Score addons can ruin the experience harder than anything else I can think of. The wow classic team is going to have to fight off addons like we do viruses on windows.
Here are my two cents. It clearly cannot teleport anyone anywhere, work across realms, make reputation on the realm irrelevant, or exclude people that don’t have it installed from participating in the human LFG process. However, the following are potential problems.
The addon communicating in secret with other instances of itself would be unfair. If they find any way to make this happen, it would give an unfair advantage to one of two hypothetical players logging on at the same time. Presumably the one with the addon installed could instantly get a fresh list of currently forming groups sent to it by another random player that has been logged in for a while via some sort of peer-to-peer mechanism.
Players of low-demand classes with the addon installed would have an advantage over those without it. The whole point of the addon is to automate communication about groups, including asking for an invite. Naturally, this would make it much easier for a rogue with the addon to beat out a rogue without it for a spot in a group on average.
It could spam people or advertise itself. People using the addon already wouldn’t notice, but those manually monitoring chat channels would probably quickly get annoyed by the addon saying something in LFG like “LF2M DPS SM Cath - Brought to you by Icy Veins!” Even Retail’s manual LFG system limits a player to asking for invites to up to five groups. Since this thing’s just sending tells, it could (presumably) ask to an invite to thirty-seven different groups in the same five seconds.
