They literally hard-coded the attitude into the clients and relays, so that it's very difficult to have a discussion about any other topic, and newbies wander off in frustration. The attrition rate is astronomic. Even my old Wordpress mommy blog had better numbers.
You have to first spend a year,
replying daily to other people's Bitcoin memes and GMs,
to get enough followers,
to be seen by enough people,
to be able to talk about sports.
But,
after a year of talking about Bitcoin and saying GM and talking about talking about Bitcoin and talking about saying GM,
you lose your ability to talk about anything else.
So, you never get around to talking about sports.
