 I know that you're aware that Senators Blumenthal, Klobuchar and I found the open market app store bill so that we could address Google and Apple and their stranglehold on that app market. So very quickly how to Apple and Google's data practices factor in to this app store and how they limit the use there and do they incentivize the app store developers to continue the monopoly over this market that they have. So how are they manipulating that marketplace very quickly? Thank you so much Senator Blackburn and we were so glad to see the introduction of the open app markets act. I think that's going to be really important not just for big data but for gatekeeper power writ large when it comes to app stores but in particular with regard to big data I think the app stores and the operating systems have this privileged position where they can treat users decisions about their data differently based on whether the app is owned by the app store company or the operating system company or whether it's a competitor. So one thing that's really important is to make sure that those are being treated the same so that we have a level playing field for competition. I think that's important in that privileged position that they exercise is important to note and you mentioned the gatekeeper property and how that would apply to other applications whether it is publishers and other forms of content development. So I think this is an important field that we get passed in on the record very quickly on filter bubbles and I know you mentioned that how do you address, how do you think we could address the filter bubbles and the platforms secret algorithms if you will that really kind of again how that would apply to other applications whether it is publishers and other forms of content development. So I think this is an important field that we get passed in on the record very quickly on filter bubbles and I know you mentioned that how do you address, how do you think we could address the filter bubbles and the platforms secret algorithms if you will that really kind of manipulate that consumer experience online. So one of the ways the big data is used is to decide what products to show the users. The platforms again are in this this gatekeeper role where they're making those decisions a lot of times that's based on an algorithm that is fed by data that they're collecting from users. So those decisions about which products to show to users, which services to offer to users those are decisions that the platform gets to make and that's limiting the options that a user sees. Yeah and I think that the open apps market act gives us that footing as I said that gatekeeper role to begin to address that so that the consumer online consumer has a more private and a more genuine experience and we're looking forward to getting that bill passed. So thank you for those comments on that because I agree with you I think the implications we're going to see at writ large.
