Collaborator omitting my name from their CV
Some of what your colleague did is unethical, some of it is not.

For listing grant funding, I haven’t seen a whole lot of official standards for how they should be presented. Listing one’s own role (PI, co-I, etc.) should be sufficient. One need not list all the principals for the grant (unless specifically asked).

However, when it comes to papers, leaving off who’s a coauthor on a paper is definitely unethical. It’s also unethical, in my view, to list a paper that you couldn’t produce if asked. So anything that’s just in the planning stage should not be listed.
