ISTANBUL, March 18 (Reuters) - Turkey's competition

authority imposed on Monday an interim measure on Meta Platforms

Inc ( META ) meant to hinder data sharing between the Instagram and

Threads platforms as it investigates possible abuse of the

company's dominant market position.

In December, the authority launched an investigation into

Facebook parent Meta over a possible violation of

competition law by linking its social media platforms Instagram

and the newer Threads.

The authority said the interim measure would remain in

place until a final decision is made, since the data obtained

and merged through these two apps could "violate competition law

and cause irreparable damage" in the market.

Separately, the Turkish authority fined Meta 4.8 million

lira ($148,000) daily as part of a

separate investigation

over a notification message that the company sends users

about the sharing of data.

The notification about data sharing between the

company's Facebook, Instagram and WhatsApp services did not

provide sufficient information and was not transparent enough,

it said.

The user notification was also designed to guide users

to approve data sharing which was not deemed sufficient to

address anti-competition concerns, it added.

A Meta spokesperson did not immediately comment on the

decisions.
