But Yahoo pretty much ruined companies they bought like Tumblr for example. I’m not saying Facebook won’t make the same mistake but so far they have done a relatively good job with Instagram and WhatsApp. Both of them are very popular and growing. Much different story than Yahoo, at least so far.
I think since they have just this year pushed out the founder of Instagram and will presumably be taking more control of Instagram, we will see how they actually do with it going forward. Up until lately, Instagram has had relative atonomy.
Yes it does. Users of the platform today are uninterrupted by ads and have no reason to think about how the platform is mining their data -- many are unaware its owned by FB.
Depending on the intrusiveness of the ads, users may opt to move to another platform, which will lead to more people being pulled away from Whatsapp. FB will have to monetize aggressively to recoup investments and keep wallstreet happy, but users may not be very receptive to ads within their messaging platform.
