EU/Ofcom could make itself useful?
Rather than chasing IE off Windows (when Apple/Google are as bad), they could mandate that Gadgets (PCs, Laptops, Phones, Routers, etc) be supported for 5 years with OS updates. They could even stipulate a Test suite which needs to run the same way (and at the same speed!) 3, 4 or even 5 years on, so we don't get the Apple IOS upgrade - lots of new features, but sorry your iThing now runs like a dog, please buy new...
Same deal with Apps perhaps - e.g. they have to support 5 year old hardware - even if it's just older versions with Security updates only.
This would be GREEN and PROTECT the consumer!
