WhatsApp is a popular messaging app that many people use to talk to their friends and family. It works on different devices, like iPhones and Android phones, which makes it easier for people to chat with each other. Some people think WhatsApp might become more popular than another app called iMessage, which only works on iPhones. This is because iMessage doesn't work well between iPhone and Android users, so some people are trying out WhatsApp instead. But Apple, the company that makes iMessage, might make it better for everyone soon, so WhatsApp might not become more popular after all. Read from source...

- The author claims that the ongoing discussion around iMessage versus SMS and RCS could be aiding WhatsApp's growing appeal. However, this is a weak argument, as it does not provide any evidence or data to support this claim. It seems more like an assumption than a factual statement.
- The author also mentions that it would be amusing if WhatsApp overtook iMessage because Apple refuses to bring first-class messaging support for Android. This is a subjective and biased opinion, as it reflects the author's personal preference for Android devices rather than an objective analysis of the market dynamics and user needs.
- The author further states that WhatsApp's cross-platform capabilities and ability to host large group chats are seen as significant attractions. However, this is a vague and generic statement, as it does not provide any specific examples or data to illustrate how these features are more attractive than iMessage or other competitors. It also ignores the potential drawbacks of WhatsApp's cross-platform approach, such as security issues or privacy concerns.
- The author finally mentions that the resurgence of international travel post-pandemic is possibly contributing to WhatsApp's growth, as the app is a primary mode of communication in numerous regions. However, this is another weak argument, as it does not provide any empirical evidence or data to support this claim. It also overlooks the fact that many other messaging apps are popular and widely used in different countries and regions around the world, such as WeChat, Telegram, or Signal.

Overall, the author's article story critics are not very convincing or persuasive, as they lack solid evidence, data, or logical reasoning to support their claims and arguments. They also exhibit a strong bias towards WhatsApp and against iMessage, which may undermine their credibility and objectivity as journalists and analysts.

Neutral with a slight positive bias.
