It's not actually the Opera Browser that is anti-flash, it’s a product analyst at Opera named Phillip Grønvold, that in a flurry of tech news reports has been reported as saying flash technology should have 'open standards'. Flash technology is a type of programming used in internet software applications. Web browsers such as Firefox and Opera incorporate Flash compatibility into their browsers to allow their product to be functional on websites that use Flash.
The reason why the 'Opera browser is anti-flash' is because it allegedly disables alternative flash technology in the application marketplace. This restricts web-browsers such as Opera from having a wider choice in how they design and implement their web browsing technology. As a matter of competition, and development, a flash design dominance could stifle innovation in flash programming.
A possible solution advocated by proponents of Opera development support the idea of open standards flash technology. According to Jake Smith, a front end web developer, Adobe tools are not necessary to incorporate flash technology into web design. Moreover, in an article posted at Opera's development website, Smith sites flash technology as being a downside requirement in web font design. (2) Clearly this belief is shared by others within the Opera corporation as well.
Another reason why Phillip Grønvold of Opera browser product team is anti-flash is because flash does not optimally support video applications. Unless flash technology is developed to a point where video flash does not use up excess hardware capacity, then it is inefficient.(1) Thus, Open flash standards in which new benchmarks can be set aside from Adobe, would enable improved product development.
Opera browser is not the first to be anti-flash, as it is preceded by another company. Namely Apple, that's computers are compatible with the Opera web browser. However, Apple's standpoint on the matter is challenged by Adam Banks in an article on Techradar.com.(3) Specifically, Banks points out Apple makes good use of flash technology and has a long standing relationship with Adobe making it an important aspect of Apple's development. Another point is that by opening flash standards, developers seeking to use other tools would be just as reliant upon new flash technology as they would on existing flash technology.
One question that one might ask is, if the Opera Browser is anti-flash, why it or Apple don't develop a similar technology that is able to compete or better incorporate flash into applicable software applications? Creating and integrating a new product line is a huge corporate move, but in theory no one is stopping the market from developing in house alternatives to the existing flash technology. In the meantime, Adobe Flash is the market maker for flash technology and new tech solutions will quite possibly have to work around that.
