That&#x27;s not a very good way to run a commercial entity. And it is also why developers should not be making the call about which browser to support and which not.<p>The reason why is that the fixed cost of a business are that: fixed. The profit is usually over-represented in the last few percentage points of the people using the service or buying the products so if you lop off some arbitrary percentage at the top that 15% of your users might be 80% of your profits. That&#x27;s a very quick way to die.
