Editing Ad blocking (section)

==Business models==
Tools that help block ads have to work on different business models to stay in operation:

* '''Free and open source:''' Several tools work under a [[Free and open-source software|FOSS]] model, powered by community contributions and donations, e.g. [[uBlock Origin]].<ref>{{Cite web|last=Pearce|first=Joshua|date=24 Apr 2020|title=What you need to know about open source ad blockers|url=https://opensource.com/article/20/4/ad-blockers|access-date=2020-09-15|website=Opensource.com|language=en|archive-date=17 August 2020|archive-url=https://web.archive.org/web/20200817140305/https://opensource.com/article/20/4/ad-blockers|url-status=live}}</ref>{{Failed verification|date=January 2024}}
* '''Whitelisting:''' Some companies maintain a whitelist of websites that allow "acceptable ads" in exchange for a share of ad revenue.<ref>{{Cite news|last=Hern|first=Alex|date=2013-10-14|title=Adblock Plus: the tiny plugin threatening the internet's business model|language=en-GB|work=The Guardian|url=https://www.theguardian.com/technology/2013/oct/14/the-tiny-german-company-threatening-the-internets-business-model|access-date=2020-09-15|issn=0261-3077|archive-date=31 July 2018|archive-url=https://web.archive.org/web/20180731213128/https://www.theguardian.com/technology/2013/oct/14/the-tiny-german-company-threatening-the-internets-business-model|url-status=live}}</ref>
* '''Subscription/Upfront:''' Some companies offer a subscription or upfront payment model for adblocking tools, e.g. Wipr.<ref>{{Cite web|title=Wipr|url=https://apps.apple.com/us/app/wipr/id1030595027|access-date=2020-09-15|website=App Store|language=en-us|archive-date=22 August 2020|archive-url=https://web.archive.org/web/20200822141141/https://apps.apple.com/us/app/wipr/id1030595027|url-status=live}}</ref>{{Failed verification|date=January 2024}}
