What they meant when they said "planets" was the 8 (previously 9, previously to that 8, previously 7...) known and named planets in our own solar system. A hypothetical "Journal of Planets" that was actually about solar system astronomy wouldn't necessarily have known what to do with a new paper about 51 Pegasi b published 30 years ago. They're thinking "when we said planets, we actually always meant solar system planets, it just never came up until now".
The reviewer of this paper is saying that by biology they always meant naturally evolved cellular biology, not synthetic biology - there's just never been an example of the latter before.
I think the take is wrong, the receiving journals should be excited to expand their scope rather than frustratedly redefine their scope more narrowly, but definitions and categorization are hard.

Who is "they", and how do you know what they meant?
The relevant fact is that the claim "Exoplanets also aren't planets" is simply wrong -- exoplanets are by definition planets outside the solar system. It's like claiming that a brown furple isn't a furple -- the claim is wrong, regardless of what one thinks a furple is.

They aren't saying that, and that isn't true.
The argument you describe is as if Neil deGrasse Tyson took a course about “How to be even more extremely and inappropriately pedantic,” and decided he wanted to become the undisputed world expert at that.
Anyone who says “exoplanets aren’t planets” really needs to think a little harder about the actual meaning of what they’re saying.
