In this case, you need to take my comment more literally.
AMD does a lot better than nvidia but amd still makes a lot of business decisions that are not consumer friendly. For example pricing their gpus a lot higher than they used to instead of more competitive to nvidia.
They do good but in opposition to open source, it is still a company and therefore not our „friend“. Open source in contrast is made by us, therefore undeniably more our friend.
It was a figure of speech, not meaning to dump on amd.
