You just claimed that out of your ass again. There isn't a single source that says tencent has a majority stake from their investment with Discord Inc.
Not even the links you provided state what you are claiming.
Tencent owns a majority stake in GGG.
Tencent has only funded Discord for $158 million. Less than 1/3 of the total funding($500 million) it has received and well below the $15 billion the company is valued at.
Either you don't know how investments and shares work, you're bad at math or both.
Is most likely that tencent has a 10-15% stake in Discord.
