Yeah, but the guy writing the article seems to be bad at math and thinking.

Can I imagine a venue kicking out 2% of their former clients on some criteria? Absolutely yes.

Kicking out 2% of website visitors may still be totally reasonable if the cost to serve them is meaningful, or if they are less than 2% of revenue.

His defense for 98% being bad is that some CSS thing people were arguing about only had 70% coverage on his website.

Our b2b dashboard didn't support Safari for a while at all and it was entirely not an issue because everyone had a simple workaround to just use Chrome and the dashboard wasn't really the main product.

I’m familiar with some venues that only admit around 2% of those who seek to attend… as I recall they command something of a premium from those “lucky” enough to make it through the door…
