After Instagram angered their users with a sneaky terms of service change, will they defect to Flickr?

Millions of loyal Instagram users might be lured away after Yahoo released a new Flickr app, The Atlantic Wire speculates.

Many users were displeased when Instagram was taken over by Facebook, but now they are threatening to leave after their photos can be sold by Instagram.

The new term of service change states:

"To help us deliver interesting paid or sponsored content or promotions, you agree that a business or other entity may pay us to display your username, likeness, photos (along with any associated metadata), and/or actions you take, in connection with paid or sponsored content or promotions, without any compensation to you."

Many of them took to Twitter to share their thoughts on the new policy, so much so that “Instagram” become a trending topic for most of the day.

One user wrote, “Instagram what are you thinking.. Of not sorted in few days I'm outie...”

Even reality star Kim Kardashian weighed on the Instagram upset:

“I really loved Instagram :-( I need to review this new policy. I don't think its fair,” she said.

Instagram’s policy comes as a shock to users who just faced new policy terms regarding photo filters by Twitter, too.

So what’s so great about the new Flickr app that it can compete with Instagram and Twitter?

Part of what has made Instagram so popular is its cool filters. Though it doesn’t have as many and they’re not as good, Flickr offers 15 different filters.

With groups, photo sets and favorites, Flickr is similar to a Facebook album, but without the annoying statuses.

Unlike Instagram, Flickr gives their users the option of how their photos will be shared through the Creative Commons system.

Flickr is a picture-based social network that was bought by Yahoo in 2005, when Facebook was nearly unknown.

"Back then, the passion around Flickr would make the the fervor of Instagram look like a 12-second flash mob in Boise, Idaho. People loved — I mean loved! – Flickr," Bits Blog's Nick Bilton wrote.

He added on his New York Times blog:

"As Flickr moves forward, it has to be careful it doesn’t try to be something that it is not. Instagram is trying to be like Twitter, while Twitter is trying to be like Instagram. Facebook is trying to be like, well, who knows what it’s trying to be? Either way, there is currently a gaping void on the Web for people to share higher-resolution beautiful photos. Flickr should be that place, as it once was. We don’t need another Web site or service to see pictures of someone’s lunch or their soy latte, or another teenager making a duck face."

Flickr now has an opportunity to be what it once was and gain the millions of users that Instagram is threatening to leave out in cold.

The photo-based site's new update came on Wednesday, coincidentally the same day Instagram announced their new policy.

It might not necessarily be better than Instagram, but it’s probably worth a try.
