How about immigration opinion? Animal rights opinion? Climate change opinion? Political views?

- "Political views" is too vague to comment on.

- Immigration opinion is absolutely grounds for changing a CEO - it affects groups of people, potentially both employees and customers of any company. If the CEOs views affects them sufficiently negatively, this should surely be addressed?

- Animal rights - possibly , particularly if the company's role is animal-related.

- Climate change - as above.

All the above might not apply to a company / CEO that is not as directly "public-facing" as Mozilla, but generally for any company with a widespread reputation to uphold and an outspoken employee base, then absolutely any of the items you listed could be grounds for change.
