Christ, no wonder you and the VRC staff are giving out such bad advice if you think that everyone has a 100Mb connection these days. This is DEFINITELY not true. The overwhelming majority of people DO NOT have a connection this good.
As an example, here are some metrics - Internet Speeds by Country - Fastest Internet In The World Map - keep in mind that people with incredibly fast connections will be pulling that average up and making it seem like the lower end isn’t as bad as it is. Hell, the main thing I hear from friends in the US is how they’re stuck on a bad provider with rubbish speeds because they have no alternative choices in their area.
