It&#x27;s easy to say this stuff, less easy to implement in a business. It depends on your demographic and your content. Take B2B sales or B2B SaaS. Enterprise users are THE main reason for crappy old browsers in my experience, so the real question becomes...<p>Are you really willing to take a 10% hit on sales?<p>You can announce EOLs until the cows come home (Microsoft has and look how well it has done them). If your product stops working, they&#x27;ll complain at you and then cancel their contract and find another provider who will support them.<p>I&#x27;m speaking from a gruelling 15 years experience developing enterprise SaaS. We&#x27;ve only just dropped IE6. It&#x27;ll be years before IE8 goes away.
