Thank you for pointing this out. It's not a problem for a lot of people but the fundamental ethics driven FOSS user should at least be made aware that he sided with Microsoft during the worst Linux is cancer era of MS PR.
I found the talk about SwiftGodot amazing. Do we really need to be reminded in this context about what the speaker did 20+ years ago? Like, any relation to the talk or to Godot AT ALL?
Cancer quote is Balmer in 2001. That same year Miguel started Mono. But he did other things that held back the FOSS movement like support Microsoft for OOXML.
"Advocacy of Microsoft open technologies edit
De Icaza endorsed Microsoft's Office Open XML (OOXML) document standard,[15][16][17] disagreeing with a lot of the widespread criticism in the open source and free-software community.
He also developed Mono – a free and open-source alternative to Microsoft's .NET Framework – for GNOME.[18] This has raised much disagreement due to the patents that Microsoft holds on the .NET Framework.
De Icaza was criticized by Richard Stallman on the Software Freedom Day 2009, who labeled him as "Traitor to the Free Software Community".[19] Icaza responded on his blog to Stallman with the remark that he believes in a "world of possibility" and that he is open for discussions on ways to improve the pool of open source and free software.[20]"
… of all the strange places to find a good summary of nice swift features.
