ice (e.g. prevention or removal of QoS degradation of IAS). Necessity refers to selection of the less troublesome solutions in network neutrality enforcement - for example, penalties should not be first on the list of regulatory tools, but rather, naming and shaming of ISPs or warnings issued to ISPs with IAS degrada- tion or network neutrality infringements. If a light touch approach is deemed insufficient or ineffective, more drastic enforcement tools can be applied (e.g. financial penalties). Proportionality refers to adequate application of enforcement measures, and that the imposed obligations are appropriate to the goals and cannot be replaced with other, less interfering and equally effective alternative actions. 8.9 Discussion Network neutrality is part of the core philosophy of the Internet network, SO it would not disappear but typically would change its definition or positioning on the telecom ("digital") market. In fact, network neutrality refers to an Internet network which does not offer any guarantees to any particular flow or content. It has sped up innovation 8 Network Neutrality in the telecom sector with the appearance of the Internet available to everyone since the middle of the 1990s. Why? Because OTT service providers do not need to adhere to strict national regulations for services provided with QoS guarantees. To prohibit censorship of content and applications or their differentiated treatment, network neu- trality (as a native feature of the Internet) was accepted on the global scene by most countries worldwide. That allows Internet traffic to traverse over terrestrial networks through different countries without blocking or filtering. Why? It is related to the free- dom of the individual to choose what they want to use as a service and which content they want to consume. Such an approach can be called "freedom" in the telecom/ICT space, in the cyber world. The cyber world by itself is mimicking the real world and all of its functions, SO freedom in the real world (to move freely, to act
