Addressing the first of your questions, no, Adobe no longer licenses any of its type library in Multiple Master format. Although Type 1 Multiple Master technology was a very promising technology over 20 years ago, it was never particularly popular with our customers nor was it supported well or at all by other applications and operating systems. Thus, that format was discontinued. Some Adobe applications continue to support Multiple Master technology, but the ability to create and use custom instances of such fonts is not available.
When Adobe re-released its type library in OpenType CFF format, for all the previous Multiple Master typeface families, all the predefined instances of the Multiple Master fonts were issued as individual typefaces. Since very few users ever used custom instances, this had minimal effect.
Thus, if you are interested in the Cronos type family, the Cronos Pro OpenType CFF fonts should meet your needs, especially since it supports many more typographical features than the original Multiple Master version. Is there anything that you think is missing from Cronos Pro?
With regards to your second question with regards to Cronos MM being free to download, just because you found something on the internet doesn't mean that it is true. Adobe has never released Cronos MM as a “free to download” product. If anyone is posting copies of the old Cronos MM fonts for “free download,” they are doing so illegally.
