The European Union (EU) is challenging Instagram over its addictive design features. Expressing serious concerns over social media addiction, the EU has demanded structural changes to the popular platform to make it less addictive. Although no specific timeline or design changes have been proposed, the EU insists that Instagram should take immediate and effective measures to protect users, especially young people, from the potential harm caused by excessive usage.

In Japan, this news would likely generate widespread debate, considering the country's traditionally cautious approach to technology's societal impacts. With a high user base of Instagram, concerns about social media dependency and its toll on mental health, particularly amongst the youth, is a persistent topic. The news could potentially accelerate discourse around evolving internet regulations in Japan.

In comparison, the US and EU have different stances on tech firms and their societal impact. In the EU, there has been ongoing swell scrutinizing tech giants and demanding accountability. The US, though increasingly critical, tends to lean more towards self-regulation by these companies.
