First of all thanks for all your kind comments. I am putting the posts back.
After all Envy was born for the Community and its existence wouldn’t make sense without its users, who provide feedback and contribute to make Envy an easy alternative to reading long howtos (which I write as well) and to long (and inevitable) troubleshooting sessions if something goes wrong (as regards the said guides). All the time I spent helping users on Ubuntuforums.org made me realise how important it is to have a quick way to install the latest release of (ATI or NVIDIA) proprietary drivers (e.g. what happens if your new card is supported only by the latest driver which is not available in the official repositories?). There is a massive request for such tools and when I read that some users got to know Envy on Planet Ubuntu and saved their computer from reinstalling Ubuntu (or even XP), I think it’s better to put back the posts on Envy. Of course you’re free not to use Envy and to read howtos (on this subject), which is perfectly fine and you’ll become more knowledgeable.
Even if such posts might look like spam (or simply useless) to the (lucky) users of graphic cards which work with (3D enabled) open source drivers, very often do they solve problems to many users (and, at least as far as I can see on ubuntuforums, most users seem to have ATI or NVIDIA cards).
P.S. Don’t worry, if you have a look at my website you’ll see that there are well visible warnings against using non-official tools in Ubuntu. Furthermore Envy has its own page on Launchpad if you want to report bugs.
