Facebook has experienced powerful pushback in response to its announced coming change in use of the personal data it collects.

Although this change would have increased the use of the collected data for profiling, the underlying wrong — the collection of the data is happening already. Collecting personal data is the primary wrong in WhatsApp. Even if Facebook decides to cancel the change, this reason to reject WhatsApp will still exist, as it has existed for years.

There are other reasons to reject WhatsApp, starting with the fact that it requires users to run nonfree client software on their own computers.
