The other folk have given some (correct) reasons why I read an opinion in your message. But, here was my thought process. If I was wrong in how I understood your message, my apologies.

>On the surface it appears

This implies an ulterior motive.

>expose flaws

As mentioned, "expose" is an emotionally charged word with negative connotation.

>in competitor's products.

P0 does not just focus on competitors products, by any stretch.

Your statement also fails to convey that they notified Apple with industry accepted disclosure practices in order to fix the vulnerabilities, rather than just "expose flaws".

Your message shows how this situation can be framed to create a negative opinion towards Google. The wording of "on the surface it appears" implies that showing that was the purpose of the message.

"Expose" is a loaded term in many cultures. In particular it means to reveal something which the other party was trying to hide, usually in an adversarial way.
