I was curious recently about how much Ubuntu has changed over time particularly licenses of software installed by default. It’s not what you’d expect.
我最近对Ubuntu随着时间的推移发生了多少变化，尤其是默认安装的软件许可证。这不是您所期望的。
Some preliminary results for packages installed by default can be seen here:
默认安装的软件包的一些初步结果可以在此处看到：
Ubuntu 14.04 codenamed trusty and 24.04 codenamed noble are exactly 10 years apart.
Ubuntu 14.04代码为Trusty和24.04代号的Noble相距十年。
GPL-like licenses still take the big chunk of software that goes into Ubuntu. The major difference with these ones and others is copyleft.
类似GPL的许可证仍然带有进入Ubuntu的大量软件。与这些和其他的主要区别是CopyLeft。
Looking at the bigger software packages/subsystems, we have:
