Some people[<i>who?</i>] believe the practice of charging for specifications has undermined the purpose of VESA. According to Kendall Bennett, developer of the VBE/AF standard, the VESA Software Standards Committee was closed down due to a lack of interest resulting from charging high prices for specifications.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> At that time no VESA standards were available for free. Although VESA now hosts some free standards documents, the free collection does not include newly developed standards. Even for obsolete standards, the free collection is incomplete. As of 2010, current standards documents from VESA cost hundreds to thousands of dollars each. Some older standards are not available for free, or for purchase. As of 2017, the free downloads require mandatory registration.<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> While not all standards bodies provide specifications freely available for download, many do, including: <a href="/facts/ITU/xnT5QSEl">ITU</a>, <a href="/facts/JEDEC/EM7UoQlJ">JEDEC</a>, <a href="/facts/Digital_Display_Working_Group/qHnWLWgg">DDWG</a>, and <a href="/facts/HDMI/HuNwzm04">HDMI</a> (through HDMI 1.3a). </p><p>At the time <a href="/facts/DisplayPort/rJSvGhBN">DisplayPort</a> was announced, VESA was criticized for developing the specification in secret and having a track record of developing unsuccessful digital interface standards, including <a href="/facts/VESA_Plug_and_Display/He2zPpVa">Plug & Display</a> and <a href="/facts/Digital_Flat_Panel/HEXGUBhS">Digital Flat Panel</a>.<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> </p> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>California Secretary of State.
