Some people criticized Zuckerberg for the tone of the tour, which juxtaposed cartoony figures and cheery banter with the storm that severely damaged Puerto Rico late last month, killing more than 30 people and leaving scores of others without essential utilities.
Franklin also teased that Spaces would also be arriving on "other platforms" soon, hopefully meaning the HTC Vive and PlayStation VR are getting in on the fun. So when you do see these 3D objects on your regular PC, you can drag and move the object around with your regular mouse, no VR headset required.
"Reading some of the comments, I realise this wasn't clear, and I'm sorry to anyone this offended".
It suggests Facebook may be unveiling new plans for Spaces during a keynote speech by Zuckerberg, scheduled for 10am PT (1pm ET / 6pm BST) that day. "People talk about cognitive security and there's a strong idea that our thinking to some extent has been hacked by this particularly angry rhetoric that shows up on Twitter Google and Facebook".
"We're on a bridge here, it's flooded, and you can get a sense of some of the damage here that the hurricanes have done", Zuckerberg said as flood waters in Puerto Rico ran past behind the cartoon duo.
In an apology, Zuckerberg pointed out the video was designed to raise awareness about disaster.
Zuckerberg said he plans to "announce some stuff I am not going to announce now" at the upcoming VR conference.

The video was panned on social media. Zuckerberg's cartoon avatar looked quite tiny in front of the dog in the living room.
If Facebook had broadcast a VR session to a test audience, someone might have noticed the inappropriate nature of the cartoonish avatars.
Zuckerberg is not the first tech billionaire to offer support to Puerto Rico, after Tesla boss Elon Musk said his company could solve the country's energy crisis using solar panels and batteries.
"This street is really flooded", added Mark.
Needless to say, many weren't happy with the use of disaster relief to sell a product.
"Facebook is designed to affect - essentially favour - incendiary material", Kirkpatrick tells The Current's Anna Maria Tremonti. More details on the experience will be available soon.
