The AGPLv3 license on #OnlyOffice’s code allows forks as long as you keep the same license, ship source, and preserve copyright and attribution notices. WTH! So that sounds to me like they are saying you can’t fork us you can just tweak and reship our product. WTF! Either you ship forkable copyleft code that allows changing the product AND its branding or you don’t; you can’t have it both ways. Forking is a normal part of the #OpenSource ecosystem.
