Sadly this is exactly what I expected when Avast took over Piriform. When I saw the new results graphics I knew it had started, the change towards CCleaner becoming another flashy fronted, dumbed down, identikit cleaner (ie "will undergo change and we will be bold") - make it look fancy to try to sell more, regardless of whether it's of use to actual users. Next step after that dumbing down in a couple of years, style and brand it as Avast cleaner. And/or integrate it into an Avast utility program or Avast AV and CCleaner becomes ancient history. CCleaner did not become a massive success DESPITE it's basic look, that was entirely PART of it's success.
And hiding results of a clean does nothing to help so called "average users". "If you ask the average person what a 'cookie' or a 'thumbnail cache' is they simply won't know". I actually disagree but, regardless, the current change means they don't even know those things exist. If they see it in the results list they can google and find out, and perhaps learn the effects. Hiding that from them means they know nothing, can learn nothing and can have no idea of possible consequences of the things they don't know were cleaned.
Oh and let's not also forget the removal of links to the builds/portable version on the download page, another recent anti-user move.
It's a classic route that is taken whenever a large company takes over a smaller successful one - small company becomes successful/attractive, large company takes over, thinks they can do better despite the small company having done an amazing job to beat the odds and become successful in the first place, interfered with product becomes less successful, then large company dumps it cos for some reason it's no longer providing the value it was before they interfered.
I'm just keeping my fingers crossed that I will be proved wrong, but the signs so far suggest otherwise
