Not quite. "Squeak" refers to the underlying system. It is the leading open-source Smalltalk implementation and has many uses besides Etoys, from web servers to embedded applications (see squeak.org). "Etoys" refers to the tile-scripting system as used for educational purposes, its home is squeakland.org

"Squeak" and "Etoys" is used pretty much interchangeably by the education community, which leads to confusion when talking to developers. That's why for OLPC we indeed started to refer to it as just "Etoys" or "Squeak Etoys". The latter to avoid confusion with "eToys.com", which is also why we try to eradicate the interCap spelling.

Yes, Etoys has been license-clean since 2008. Squeak took a while longer, it is license-clean as of version 4.0 (released in March 2010). Which not everyone might be aware of, yet.

>> While Scratch is less powerful than Etoys, it certainly is more polished and easier to get into. That was one of its design goals - to let teenagers have immediate fun in an hour after school, without needing too much guidance. Etoys OTOH was designed to be used by a skilled teacher as part of a larger curriculum - and it is a prototype that "escaped into the wild" without seeing much polishing.
>> So I can see why teachers love Scratch. I love Scratch, too. It requires much less effort to get started. Certainly enough, Scratch comes pre-installed on many OLPC builds (and OLPC recently sponsored me to add basic Journal support). Besides, the xo bundle can easily be downloaded.
>> But for inclusion in Sugar itself there are more criteria than just ease of use. Like the willingness of developers to work in the Sugar community. Which is almost synonymous to the development process itself being open. Or making serious efforts to "fit" into Sugar - be that UI design, or supporting collaboration etc.
>> Etoys is working in that direction, and also welcoming contributions. The Scratch developers have other priorities. In a way, Scratch is so beautifully simple *because* its development is so tightly controlled. It's like an Apple product compared to a Linux one. The Linux program might be more powerful, but many people would still prefer the simpler, polished, less confusing Apple product. Others see beyond the flaws of the Linux program, and some dive in and help improving it. Given time, money, and effort it might even attract users in the general public ;)

Well ... a page that works out-of-context is way harder to make than answering a concrete question here. So I abstain from that for now. Point people to the archives if needed. Or make a blog post that points to the archive ;)
