Facebook-owned popular messaging service WhatsApp has been found
blocking links to rival messaging app Telegram. Although you can
send/receive Telegram links, they appear as non-clickable (just plain
text) and you cannot copy/forward them (see screenshot below).
In general, it looks like any link having 'telegram' as a sub-domain
is affected. Only WhatsApp's Android app is currently exhibiting this
behavior, which was first spotted by users on Reddit. A new update
pushed yesterday is said to be the culprit - it didn't bump the app
version, which remains at 2.12.367.
On its part, Telegram has confirmed the situation, but the company
doesn't seem much concerned. "Typically after a media backlash, FB steps
back and blames their intelligent filtering for the problem," a
Telegram spokesperson said. "We expect the same to happen this time as
well." Facebook and WhatsApp are yet to comment.
It's worth mentioning that Telegram recently received some bad press
over the fact that the company knowingly allowed members of the Islamic
State terrorist organization to use the app.
