What's your opinion now? Do you recommend "Clean my Mac"? If No, why exactly not?

The thread may have started in 2009, but there are many more recent posts. There are ongoing reports of problems with this app, both in this forum and elsewhere. I would strongly recommend against using this app. It's not necessary or effective, and can be harmful if not used with extreme caution.

You don't need "cleaner" or "maintenance" apps to keep your Mac running well, and some of these apps can do more harm than good. Some can even degrade, rather than improve system performance.

Some remove files/folders or unused languages or architectures, which does nothing more than free up some drive space, with the risk of deleting something important in the process. These apps will not make your Mac run faster or more efficiently, since having stuff stored on a drive does not impact performance, unless you're running out of drive space.

Some of these apps delete caches, which can hurt performance, rather than help it, since more system resources are used and performance suffers while each cache is being rebuilt. Caches exist to improve performance, so deleting them isn't advisable in most cases.

Many of the tasks performed by these apps should only be done selectively to troubleshoot specific problems, not en masse as routine maintenance.

Mac OS X does a good job of taking care of itself, without the need for 3rd party software. Among other things, it has its own maintenance scripts that run silently in the background on a daily, weekly and monthly basis, without user intervention.

that means you also don't recommend CCleaner (popular Windows app now available for OS X in app store)?

That is correct. You don't need any such apps to keep your Mac running well. Many of these apps leverage off the old Windows mentality of having to "maintain" the system. It's not necessary on a Mac.
