See, this is one of the many reasons why people left Lemmy. Stuff normal people laugh at. Not that I like this stuff all the time, but it is funny seeing it from time to time.

I am a nerd, but I like my feed versatile. It was interesting at the start when the normies were here with the shitposts and all that, and they tried, they really did... now this place is just boring and stale AF.

I bet you're the life of the party.

It's a well known facts, specifics are not necessary, I could list hundreds of other cases where I can prove that. I seriously doubt Finland would be an exception from that.

1st world countries profiting on the backs of 3rd world ones is a completely unknown concept for you I guess.

It's probably a proprietary connector made specifically for Yamaha, or Yamaha made it themselves. It's loosely based on car connectors from what I can see, but I don't think you're gonna find much info about it.

I'd just go in "guns blazing" with this thing. If there is a replacement for it and it's fairly cheap I mean. If not, I'd try and pry the silicon off with some of my DIY tools for these sorts of situations.

I wish to know how to open this socket to access the rubber/silicone seal inside, and to know that first I need to identify the name of this connector

What exactly do you mean by this, is the connector sealed?
